Andrew, it goes without saying it must be the same image for comparison purposes. You know, apples with apples, oranges with oranges.
IF the issue is a comparison with images, sure. But that's not the statements we see or hear from others. They show a gamut plot of two color spaces. They jump to the same conclusions you did about the size of the two triangles and say "
Adobe RGB has more colors than sRGB". This thread, which has been very useful, illustrates that without an image, which has a gamut, the statement alone doesn't make sense.
Ah, the lengths you guys are going to go just to avoid admitting that, in plain English, and for all practical purposes, "Adobe RGB has more colors than sRGB."
I disagree. This is like Gary saying "just tell me what's going to be better, Adobe RGB or sRGB" based on his flawed testing. And no, not for all practical proposes, in specific situations with the rules set so no goal posts get moved. Without assumptions.
The blanket statement that a bigger triangle means more colors doesn't wash. It has NO colors. It's a container. Some of us are just tying to be accurate in our language.
And here's another question: what about encoding?
We have an image (Bills Flowers) in 16-bit Adobe RGB which we convert to sRGB. We then convert his Adobe RGB image to 8-bits. Could the sRGB image have more colors?
