Help with coloring a button?

Questions & Answers

I’m trying to make a plain GUI button that is blue, with no text on it.
Here is my code,

    var btnTexture : Texture;
    var btn_Color : Color.blue;
    function OnGUI() {
        if (!btnTexture) {
            Debug.LogError("Please assign a texture on the inspector");
            return;
        }
        GUI.Color = Color.blue;
        if (GUI.Button(Rect(10,70,50,50),btnTexture))
            Debug.Log("Clicked the button with an image");
        if (GUI.Button(Rect(10,10,100,30),"Test"))
            Debug.Log("Clicked the button with text");
    }

Unity says that “The color blue does not denote a valid type.”

I’m going to have multiple colored buttons in this script. Red, orange, yellow, green, blue, and purple. Is there a way I can make it so each button has a different color? Also, how do I even make the button have color because Unity makes an error.

It’s not Unity making the error, it’s your code. Try:

var btn_Color : Color = Color.blue;

The “official” way to make GUI elements different colour would be to use GUIStyles.
