PS. First piece with colour. There was actually a process which came up with some unexpected results. Started out as a hexagon, converted that to a cube, cut each face into 4 smaller squares and slapped a circle on each (ovals with perspective). So actually there is no circle in the middle there, that's 6 ovals overlapping. And there are no triangles, at least none that i drew, those are overlapping squares. It's called take a minute because it'd be cool if you took a minute to look at the different things I put on there.
Colour utilizes a colour wheel style which shows how colours mix together. Red mixes with yellow to get orange yellow mixes with blue to get green blue mixes red to get purples.
