What are available colors?

Non-metallic: Neon inks (pink, yellow and green), CMYK (white, black or other CMYK colors), PMS (Pantone) inks.
What is the difference between CMYK and PMS color?
PMS (Pantone Matching System) is much brighter and thicker than CMYK, and the texture is similar to color foil. The comparison of PMS color with CMYK above shows how much punch you lose in printing from a Pantone ink vs CMYK color printing.
However, in order to print each PMS color we create a plate and then proceed with silk printing process, whereas CMYK does not require any plates and has different printing process which cuts down the cost.
