Detect Magic makes my character's eyes glow blue. This is a homebrew rule that my group decided on because my Detect Magic comes from an Invocation.
This sometimes can be very inconvenient, because it makes it abundantly clear that they have some kind of supernatural sight. Could I use Thaumaturgy, which can alter the color of my character's eyes, be used to mask this effect (or at least if it can't stop the glowing, change the eye color to that of my normal color)?
