My question stems from recently seeing color_theme tags added to posts, looking at which, you'd struggle to say that there's a deliberate artistic choice to theme them after a single color as they actually don't contain much of that color, such as post #6779771, post #6776670, post #3393346, post #6732311, post #6409152, post #6748744, post #6764453, post #6765059, post #2301133 and post #3925928. There are way too many examples to list them all here, honestly.
I think artworks count as color-themed when a color takes up the majority of an image, preferably something like 60-70%, and optionally we can see other techniques that the artist has gone out of their way to use, like shading and lightning of a single color, changing the subject's palette to a given color, surrounding it with a matching background, adding some objects of that color, and so on. I'm not trying to say that these should be hard requirements for the posts to count, just listing the things that might make an image color-themed. I hope you get the idea.
What I described are the kind of images I'm hoping to find when looking up green theme, for example, but if this goes on, then it's going to only get increasingly harder to find those among images that just have a character dressed up in a green sweater, or have a patch of green in the corner.
And, can a single post really be tagged with two color_theme tags at once (post #6773841, post #2932071, post #1200912)? In my opinion, either one color_theme tag should be used or none at all.
