Bivariate Color Scheme

[scoonts3]

Could the method be shared for making the bivariate color scheme? I would like to adjust the background colors

I would still like to see the process for making a bivariate color scheme from scratch, but I have done a quick workaround by swapping the channels of Blue and Red in the npy file. Since a lot of our samples are plotting along the red and fushia colors, we needed something more visually distinct in that area.

The zip file has the .npy file if anyone wants a different color scheme. And here's two images to show the piper plot + Frazee diagram and how we have used the RGB codes to plot our samples with depth for one well.
