Quad with texture without lighting effect

Hello amazing BabylonJs experts!

I tried googling and searching this forum but I couldn’t find a good answer to this question. What is the most performant way to display a quad with a texture on it but without the lighting effects like specular, ambient lighting etc? If I have a full red (0xFF0000) circle on a texture, I would like to display as that color without it being affected by lighting. I hope I’m making sense. I would like to have multiple quads with different colors and each texture would have different colors in it. Here’s a good example. I would like to achieve this:

I really appreciate your help and insight!

don’t set a diffuse color, only an emissive one

you can also set the light specular color to black
