For what it's worth, these are the out-of-domain sRGB calls, evaluated
under assumed_gamma 1:
customTextures.inc:
srgb < 1, 0.9, 0.65> * 1.3 = rgb <1.8233, 1.4313, 0.6829>
srgb < 1, 0.9, 0.65> * 1.15 = rgb <1.3758, 1.0815, 0.5186>
pentagramObject.inc:
srgb 8 = rgb <131.4473, 131.4473, 131.4473>
srgb 3 = rgb <12.8298, 12.8298, 12.8298>
pumpkin.inc:
srgb < 1.5, 1, 0> = rgb <2.5372, 1.0000, 0.0000>
