I know, but since the intensity is unknown for the first color, wouldn't this make the intensity parameter also be unknown, except that it should be exactly half of whatever the first one is?
I don't think there is any way to calculate intensity from wavelength and purity as the only information?
I would imagine that in lasers particularly the brightness is very crucial, e.g. a laser class III wouldn't be that bright, but a class IV of the same frequency would be much brighter?
I think that would depend on your definition of a color, if the definition includes the attribute brightness, then a color with a different brightness would implicitly have to be a different color.
However my question is simply, what does a color with half the brightness of a dominant...
Forgive me if this is the incorrect section of the forum for a question like this.
If I already have used the CIE Chromaticity diagram to plot a color with dominant wavelength of 600 nm and maximal purity, how should I proceed to describe a color with half the intensity of said color -- i.e...
