What are the semantics in HLSL?

I have managed to create my first shaders, and I do not know what to do. So I was wondering what the semantics are.
struct colores
{
float r,g,b,a:COLOR; <<<<<<
};
float4 mainPS() :COLOR {
//colores salida;
colores salida = (colores) 0;
salida.r = 255.0;
salida.g = 0.0;
salida.b = 0.0;
salida.a = 1.0;
return float4(salida);
};
technique mat {
pass p0 {
//CullMode = None;
//VertexShader = compile vs_3_0 mainVS();
PixelShader = compile ps_3_0 mainPS();
}
};

| Created your own Shader, but don`t know how to use it. |

| That shader just changes the color of the material, I want to know what the semantics are. |

| Hiya, COLOR, which is the same as COLOR0 refers to the rendertarget ( or backbuffer ) to output to. If I remember correctly for shader model 3 you can bind up to 8 rendertargets which would be accessed in the shader as COLOR0 to COLOR7 which can be useful for multiple render targets. |
