To discuss this we often imagine the spectrum as having three thirds, a blue region, a green region and a red region.
In an ideal world a magenta colorant would only absorb in about 1/3 of the visible spectrum; the green area. An ideal magenta would absorb totally in the green area and not absorb at all in the other two thirds of the spectrum. However, in practice, a magenta colorant will not absorb perfectly in the green region and will exhibit some absorption in the other two thirds. I hope this is what you were looking for.
Why was there so much green in the bar chart of the spectrum for magenta?
