Can't prevent same color random generation.
Hello. I'm trying to generate bgcolor and textcolor using a list filled with color codes. The colors will be updated every seconds. What i get is bgcolors and textcolors generated same in many cases so the text can't be read. Here is my code:
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class ColorText : MonoBehaviour {
public GUISkin mySkin;
public GameObject obj;
private Color clr;
private Color txtClr;
private string clrName;
List<Color> colorList = new List<Color>(){
new Color(0,0,255,255), // mavi
new Color(165,42,42,255), // kahverengi
new Color(128,128,128,255), // gri (192,192,192 gümüş)
new Color(0,128,0,255), // yeşil
new Color(128,0,0,255), // bordo
new Color(255,165,0,255), // turuncu
new Color(255,192,203,255), // pembe
new Color(128,0,128,255), // mor
new Color(255,0,0,255), // kırmızı
new Color(64,224,208,255), // turkuaz
new Color(255,255,0,255), // sarı
new Color(255,255,255,255), // beyaz
new Color(0,0,0,255), // siyah
};

Comment
Color uses float values between 0 and 1, Color32 uses byte values between 0 and 255.
