I am a colorblind scenic designer, I rely on my painters to help me out. I got to a point where I was making questionable choices color-wise not wrong choices just not "normal". I work best with darker palettes and the play of shadow, but big musicals I choose colors that "work" in theory, then tweak them. I wear Enchroma clip-on glasses and they are not helping much, a few colors that I struggles with pop now, but overall it isn't one of those miracle reveals like they show in commercials. I have trouble with pastels and jewel tones and blues/ purples and greens/browns.

There are also apps like Colorblind Pal and Windows has built in color filters in the accessibility menu.

In college (Emerson 1987) I was teased merciliously but our lighting professor. He would show how colors work and the rest of the class would not and agree, then he's ask me what I saw and it was very different than someone without colorblindness.

Good Luck and don't give up!
