Suggestion: Black and White Pictures can be colored (?)

[Tri-Iris]

I am not sure how to explain this feature well, and it might be a bit more complicated

When you take a black and white photo, you could then add color to it via a new block that takes the specific value or the crafting table. So the black and white photo will turn this. Into this I'm not sure how you could do specific colors for specific value, but it can be seperated from light vs. shadow. I used gradient maps to do this. So it would look like these.
