I dont know how pls help

I have tried to find it on youtube but nobody answered. I added a mesh object and changed its color to pink and appended a nother mesh object thats white and its now pink and when I change its color it changes the other meshes color im new to blender so any answer will help

You should have posted this in the support materials and textures category (not off topic).
Anyway it sounds like both your objects are using the same material. Go to the material tab in properties window and underneath the material slots list hit the new material button (copy icon). It will make a new material with which you can change the colour independently.
If this is the answer I suggest you watch some basic tutorials :slight_smile:

thank you but it didnt work I made more materials but all it did was change both colors when selected but i will post it on support thank you
