I am new to shaders but i want to have a toon shader on everything, it works and it looks cool, but i want different coulours. so i go to change the couler to red and everything changes to red. Does anyone know how i can make everything different coulers while still using the toon shader that comes with unity.
You need to create one material for each colour that you are after. Simply add a new material, and select the toon shader. You can then change the colour on that material and assign to your object(s).
Ideally though you should reuse the same texture atlas where possible to reduce the number of draw calls. This is especially important for mobile games.
