[chimerax-users] cartoon selection by color

Hi, my name is Mike and I placed some atomic (cif) models in my chimera session. Also I performed manual coloring of some protein domains (watch the picture). Now I have realized that I want to change uncolored parts (#d2b48c). So manually it will take a lot of time (i have a lot of these models), is there any way to select by cartoon color. I imagine this as some command or script like: "sel by color #d2b48c" and after that i go action color and choose my desired color. Please help me.
