How to make part colour appear the same on screen?

Not sure which category this issue falls into, but

How do I make it so that when I screenshot a part and I get its colour, it should be the same hex as the one in Roblox Studio? (example: if the part had a colour value of #e4e4e4, when I screenshot it and put it in an image editor and get its colour, it should also return #e4e4e4)
