Change background color of a GUI.BOX C#

Hey, ok, so my question is, how to make a notice able color change on a GUI.Box, I can easily change the color with a button by making the follwing code. But it doesn’t seemse to be notice able when I’m changing it on a box. How should it be done, if I want a noticeable color change on my box?

GUI.backgroundColor = Color.red;
GUI.Box(new Rect(10,10, healthBarLength,20), currentHealth+ "/" +maxHealth);

Thanks in advance.

You need to use a GUISkin that is predominantly white and grey. GUI colours are multiplied, so they don’t affect black and aren’t very noticeable on dark elements.
