Hello. I'm rendering a text with a DDS file texture that has Alpha enables so it can render letters as quads. Im using DDS with no compression for quality reasons.
The resulting image will be r,g,b beeing 0 and alpha the surroundings the rest of thexture that is not character body.
When the imagine has r,g,b = 0 the text is back with correct Alpha but when I try to modify the r,g,b to any value it also colores the alpha zone even if I keep alpha at the same value.
The thing is that I want to make different colored characters and I dont understand why I cant modify different pixels after Sampling the texture.

colorOut = float4(0.7f, 0.7f,0.7f,colorOut[3]); // here I try to color the text by overwriting a given pixel that by default mapped from texture should be black (rgb 0 and custom alpha).
