Yes, you read correctly. But let me explain why I want this.
If you have textures with glowing lines, such as the default...

The shaders make it glisten if you face the sun.
However, with something like Squideey's textures...

They're just the same, boring shade. You can see this for yourself.
If this is possible, that would be awesome. I probably wouldn't even mind having to make them myself. If they exist already, that's even better.
