Remix this project and try using only 3 colors, it doesn't have to be the same palette I have here. Just try it.
I made this with 3 colors, try making one with 3 colors instead of 4 if u cant do that then thats ok, this is a harder challenge than the original project (great project by the way :D) also, view it in full screen so the candlestick doesnt look like its changing width
