I’ve been in similar situations in large or semi-large chat channels when you want to adhere to something and give the possibility to others to adhere similarly without flooding the channel with messages simply saying “me too”. So attaching an emoji reaction feels more adequate, that way anyone can just append their own and you can see groupal adhesion directly. Sometimes 💯 works, but it sometimes doesn’t.
EDIT: the more I think on it, the more an emoji saying “+1” feels like it should fill that need when 💯 doesn’t. Maybe someone should propose this to the Unicode consortium



When you mix paint, you mix pigments that each absorb certain colors, so they won’t reflect it. You’re subtracting colors to the ambient white light that reflects a smaller and smaller portion of the spectrum on the painted surface, and if you mix enough colors you substract most of it and get a dark brown or even black. When you encode rgb values for a screen, you tell pixels to add colors to the light your screen is generating, and if you add enough you get a white light.
