I put some 1/8 minus green filter on my H600c (they do sell unfrosted versions now) and it is noticeably rosier than the 4000K 219Cs and LH351Ds (including sliced 351s) I have in several lights. Experimented with adding some diffusion film to smooth out the beam but the tint shift is minimal enough that I’ll stick with the increased throw of a clear lens.
