I've been looking for a while now trying to change the color of a mesh to a flat predefined color using Hex color code. It doesn't specifically need to be a Hex code, but I need a way to change to an existing color/material using a shader. Does anyone know how to do this or even beter, knows a place where I can find info on the general shading language? I've looked through godot Docs but couldn't find anything helpfull.
