Just key urine colour chart into google images and prepare to be amazed. There are so many different charts and blogs and experts. Who would have thought it!! Today I saw an article in The Guardian that inspired to be to make this search. It turns out that there is a new urine colour chart from a clinic in USA that allows you to make a self diagnosis of your health based on the colour of your wee. A case of cross-media colour reproduction if ever I saw one (a poor joke that, for colour imaging scientists who may come across this blog).
I’m not sure it’s news though since there are a plethora of interesting charts for this already in existence and according to The Guardian the philosopher Theophilus noted the medical value in looking at the colour of urine as long ago as 700AD. However, if you have strangely coloured urine you might want to have a quick peek at The Guardian article to put your mind at rest (or not, as the case may be). Mine, for those who are interested, is sometimes clear but sometimes yellow verging on orange which is, I believe, because I don’t drink enough water. If you have blue urine it’s time to worry apparently.
I don’t just blog about flags and taxis – it just seems like it sometimes.
But today I came across a news story in the Express and Star (a newspaper in the Wolverhampton area of the UK) about a review of rules permitting taxi drivers in Dudley to use only white-coloured cars. The taxi association says that white cars are more expensive because of the popularity of the colour – with some even forced to respray their vehicles to comply with the rule. The single-colour scheme was introduced in 1996.
Just put taxi in the search box (at the bottom of the page) to see my other posts about taxi colour controversies. Or don’t, if you have a life to live.
I blog about anything related to colour and I am interested in all sorts of aspects of colour whether they be based in arts and design, cultural studies, evolution, chemistry, physics, biology or technology. But a couple of themes keep cropping up and I end up posting about them at regular intervals. So, in 2012 I posted about the historical development of the UK flag – the union jack. And then earlier this year I posted about an article on the BBC about the possible redesign on the union jack is Scotland votes to leave the United Kingdom in the forthcoming referendum there. Some of the designs that were being put forward were really horrible. Perhaps I am too attached to the union jack. A few days ago I came across another BBC story which included 25 readers’ designs for the union jack should Scotland leave. . I must say I much prefer the readers’ designs rather than those previously proposed by experts – the BBC reliably informs me that such experts are known as vexillologists. I like this flag (by David and Gwyneth Parker) – where the blue of Scotland has simply been swapped for the green of Wales, thus preserving the traditional look. (If you wonder why the green of Wales is not in the current flag see my earlier post.)
And I also like the following design (by Matthew Welch), where England and Wales are represented in the top left and bottom right corners respectively and the diagonal stripe represents Northern Ireland of course.
You probably have to be from the UK to understand this humorous design (by Al Main).
You can see all 25 readers’ designs at the BBC here.
If you are interested in vexillology (is that a word?) you may like to read another BBC story about a potential new flag for Norther Ireland. And finally, I was interested that the CIA apparently has a flag database that it makes available to the public.
Could we have developed currency around elements other than gold and silver? Why couldn’t we have coins made out of platinum, for example?
Interesting article today on the BBC website interviewing Professor Sella (University Collage London) about why, of the 118 elements of the periodic table, it is gold (alongside silver) that we value and use for currency.
According to Prof Sella there are reasons to dismiss all the elements apart from gold and silver. For example, you couldn’t use elements that are gas (such as neon) or liquid (mercury) as currency because it would be impractical to carry them around. Several others (such as arsenic and the other liquid, bromine) are poisonous and so could not be practically used. The alkaline metals (those on the left-hand side of the periodic table) are not stable enough (they react with too many other elements). And, of course, say no more about the radioactive elements. Some of the so-called rare earths (such as cerium) could be used but they tend to be even more rare that gold and are actually quite difficult to distinguish from each other.
Prof Sella also postulates reasons for dismissing the 40 transition and post-transition elements such as copper, lead, iron and aluminium. Many are hard to smelt (needing temperatures as high as 1000 deg C) such as titanium and zirconium or hard to extract such as aluminium. Iron is easier to extract and smelt but rusts too easily. Iron is also too abundant.
Prof Sella lists the 8 noble metals (platinum, palladium, rhodium, iridium, osmium and ruthenium, gold and silver) as contenders. However, with the exception of silver and gold they are too rare and have other problems (platinum is hard to extract and has a very high melting point for example). So this leaves gold and silver. The choice of these metals is not arbitrary. It turns out that they have exactly the right properties that we need. They are stable, chemically uninteresting, rare (but not too rare), safe, relatively easy to extract, solid at room temperature and with a reasonably low melting temperature.
The article also explains why gold is golden in colour.
Just read a really informative article by David Airey – an independent brand identity designer – about colour and brand identity. In his article David reiterates some ideas I heard from Laura Hussey in Design Week (and recently blogged about); that is that some companies such as Oxfam and The Guardian are rebranding with a rainbow colour palette. As David writes: “Multiple colours speak of choice, variety and diversity. Think Google, NBC, eBay, or MSN to name but a few that use more than two colours to express their breadth.”
However, David’s post goes further to describe some of his own work with Halcyon coffee and the use of a range of different colours: “The colours used within the brand and environment were derived from, and act as a subtle nod towards the diverse colour palette used during Britain’s great creative periods of the past — our Halcyon days, mixed with those we see around us today.” Definitely worth having a read of David’s article
Some of you may recall that last year – a big year for the UK with the Olympics in London and Queen’s jubilee – there was a lot of waving of British flags. I posted about how the flag was derived historically and noted the absence of any representation by Wales. For those who are less familiar, the United Kingdom is a union of four countries (England, Scotland, Wales and Northern Ireland). By contrast Great Britain is just England, Scotland and Wales (not including Northern Ireland) and the British Isles is a geographical feature that includes the United Kingdom and the Republic of Ireland. Simple?
Next year the Scottish people be asked if they want to be independent. If they vote yes (in my opinion this is not very likely, but possible) it will signal the end of the union of Great Britain and Northern Ireland. Today the BBC ran a feature about possible new designs of the new flag. I wasn’t very impressed by any of them, including the horrible one below. Try reading my post first and then the new BBC article.
An article in Stuff reveals what 3D Systems claims to be the world’s first continuous-tone full colour 3D plastic printer, called the ProJet 4500.The ProJet 4500 offers full-colour parts with colours that are able to blend into each other with gradient transitions.
The weekend of the 22nd November saw the school of Design host the Leeds Sustainability Jam 2013, part of the Global Sustainability Jam taking place simultaneously across the world. A “Design Jam” is similar in concept to a Jam session in music: people come together, bringing their instruments, skills, and open-mindedness. Someone sets up a theme, and everyone starts to Jam around it and together you build something which none of you could have built alone.
The Leeds Sustainability Jam involved a gathering of students and non-students from different areas of study, research, cultures and experiences. The design-based approach to creativity enabled everyone to participate in the discussion of sustainability and consider the environmental, social and economic aspects. Throughout the weekend the emphasis was on “not just talking but actually doing”. By the end of Sunday the teams had turned their ideas into concrete designs or plans of action which could be shared with the global design network and then realistically put into action the next day.
The resulting projects from the Leeds teams included “Be a good Bean”; a network of sustainably sourced local suppliers all connected by a cup, “The Food Experience”; a system of events making lunchtime an experience to enjoy, reconnecting people with the idea of food as being an experience in itself, and “Walk-in Wardrobe”; a university clothes sharing scheme, initially starting with jumpers, where people get to rethink their perception of fashion, consumerism and ownership.
It is now up to the teams to implement these projects across the University campus and local community!
