I've decided to make a tessellating arrows pattern to see how different colours look with it. To change the colour, press change colours, then drag the sliders to experiment with different colours. Colour suggestions (These will look good, even if you can't get the exact right values): 1) Colour 1 red: 216 Colour 1 green: 0 Colour 1 blue: 131 Colour 2 red: 110 Colour 2 green: 0 Colour 2 blue: 48 2) Colour 1 red: 192 Colour 1 green: 133 Colour 1 blue: 211 Colour 2 red: 220 Colour 2 green: 224 Colour 2 blue: 255 3 - by @supercupcake00789) Colour 1 red: 12 Colour 1 green: 255 Colour 1 blue: 130 Colour 2 red: 123 Colour 2 green: 190 Colour 2 blue: 188 This project has lots of lag; my computer has reasonable grunt power and takes just over a second to render the arrows.
