How does colorised texture work?

Hi, I want to know how colorised texture works exactly. I read that the texture is first converted to gray scale and then the color is applied on top of it. I tried doing that, multiplying color value with gray scale texture color values. This doesn’t work. I also read that same hue from color is applied to the gray scale texture. Can anyone explain this? Do we need to add colors in HSL space?
