Six colour limited palette

I’ve been tinkering with a very limited 6 colour palette for quick and secretive sketches….in a cafe I like to add colour if I can but sometimes don’t want to draw attention by unfolding a larger palette. That’s where the “mini” palette comes out to play, the tin cost about $4 and the lid and base were already coated with enamel paint so I just put a couple of strips of blue tack on the base. The tin only holds 6 half-pans and is small enough to fit in the palm of my hand….the below sketch is on an A6 notebook which hides inside my fauxdori, combined with a small waterbrush I can happily paint…. Colours I have below are: Hansa yellow medium, Burnt sienna, Permanent rose, Winsor red, Pthalo blue (green shade) & Ultramarine blue. The sketch was drawn with my TWSBI Eco fountain pen and EF fude nib in De Atramentis document black ink.
