Re: Color contrast (Minimum)

So what were the original color values for the reds? 

I’m trying to understand how the contrast algorithm is effected when the example becomes black and white.
If it’s a luminosity scale (i.e. values only are measured), then theoretically shifting or removing the hue should not matter. If it does, there is an issue that needs to be investigated.

Hope this makes sense.
