You need to change the values in which the blue color is indicated. If I remember correctly, it will be Stage1 and Stage2. Do not change the rest.
For red, try specifying texture = "# (argb, 8,8,3) color (1.0,0.0,0.0,1.0, co)".
Most likely, you will encounter another problem. The color you specify will be displayed only if the character is near the hood.
Does anyone know the solution?
