Confused about CC glass

CC glass bases height on luminance values. Brighter pixels represent higher points, while darker pixels represent lower points. However, I'm curious if you have a text layer and put a cc glass effect on it and the bump map is set to the text layer with a blue fill color, how is it basing off the height?

Your blue text still has a luminance value; color can't exist without some luminance, otherwise you would see black. Check out this little screen recording to see what I mean–in the color picker, switch from adjusting Hue to Brightness and you'll see how that value affects the displacement.

Thank you so much for the reply! Now I understand why there was a bump math to begin with! Could I ask why there are holes inside the letters when the color is brighter? Is it to express higher elevation?

You're welcome! With displacement, you can always push things too far, and I suspect, given the settings and the size of the text, I simply pushed the displacement more than the text could handle. But hey, maybe you want to create this effect intentionally, it is kind of cool looking 🙂
