Sprite.SetColor issue

[CJ_COIMBRA]

Hi.

I am having a bit of a problem on this situation: I have an animation with a few frames that should be reused with different tints but I couldn´t match any of the colors the designer provided as RGB values. I did some reading on the subject and it seems that SetColor multiplies the current color of the sprite by the provided values.

Sample image to be tinted


Colors that I want to achieve after using SetColor (the characters are irrelevant please ignore them)
 

So how can I get the correct RGB values to use with SetColor in order to get my desired colors?

Thanks.

Have you tried making the original image to be tinted greyscale? Then you should be able to set it to any colour you like. Alternatively this frag shader should work ( although I haven't tested it)

#version120

uniform sampler2D texture;
uniform vec4 tintColour;

void main()
{
        //get greyscale value
        vec4 texColour = texture2D(texture, gl_TexCoord[0].xy);
        float amount = dot(texColour.rgb, vec3(0.299, 0.587, 0.114));
       
        //set pixel to tint multiplied by value
        gl_FragColor = vec4(vec3(tintColour.rgb * value), texColour.a);
}

Did you try making your image white/gray and setting colors on it instead? That might be better.
In normalized 0..1 color values it's:
original.r * vertex.r = result.r
same for other channels. You have original and result so you can find vertex.

Thanks for the suggestions. This was the way to go.
