vmt is going to work, double click it, and open it up in either VTFEdit or Notepad, or any other text editor. We'll also be changing our "Surface 1" parameter to "Concrete". For my orange texture, we'll be checking off "Translucent" as our texture isn't translucent. So our base texture should just be "orange". We want to remove everything before the file name, in this case, orange. We won't change much, but the one thing we do want to change is the "Base Texture" parameter.

Click "Tools" and then click "Create VMT". We aren't done yet though, custom textures require a. I'll name my file "orange", then click "Save".

Since we aren't going to change our texture, we're just going to save it. You'll get these list of settings that pop up. Make sure your texture is a size that can be divided by a power of 2 Sizes like 512x512 and 256x128 images will work, but 292圆00 or something like 48x72 won't work. For me, I'm going to go to where my orange color is located on my PC, and then double click it.

Say I wanted to make this full orange color into a texture
