Going back to your post upthread - if you hold up a green card and a red card, they might have the exact same tonal contrast, such that viewed in black and white, they look identical. The difference between such cards would therefore be the hue (colour).

"- if you hold up a green card and a red card, they might have the exact same tonal contrast,"

Is that maybe the reason why Specsaver/opticians use those 2 colours of lights during any test/examination I wonder?.....just a thought.

We would see that there was no difference in contrast between the red and the green, as sooon as you removed the colour.

Rule of thumb in nature - if an animal or group of animals are coloured, then it is a good bet that they have colour vision.

They don't, as they stand. If you want them to have different tonal values, add some black or white to them.

Well, I live in Scotland and I've never seen one of those before!

Just looked at this thread as I had been thinking about the OP question.
I'm none the wiser now!
