If you are talking about the use of various colours in different combinations, the term "colourway(s)" is quite common in some areas of design. It's used particularly with fabrics and clothing, but also for interior design items like rugs and kitchen fittings. It might be a suitable term for your presentation.
For example: "For this range of chairs we have three new colourways; red and blue, red and white, and black and white".
