Someone asked me to explain some pretty basic theory, and indeed I did, only to be told by a third guy I was wrong. Wouldn’t say how though, haha. It went something like this:
"All colors have a hue, saturation and value (quick language question: brightness is the same as value?), and therefore all objects irl. These qualities are independent from each other. If you put two objects of different hue and saturation, but with the same value (is that proper use of the word anyway?) in the same environment, lit exactly the same, and took a black and white photo of them, they’d indeed look the same. If the hue and/or the saturation was the same, but not the value, they’d be different.
In addition to that, the “intrinsic value” of an object’s color adds up with the light that’s hitting it, rendering the value that reaches our eyes. This means that two objects with different value can in fact look the same, if put in different environments. And ofcourse that two objects with similar or exactly the same value wouldn’t, unless the light hitting them was similar or the same."
Is this wrong? Am I retarded?
