Reply to comment by Oscar_Cunningham in [OC] Inspired by movie barcodes, I made some emotional barcodes for books by Campbell_MG

For what it's worth - it's two different blues!

The positive primary (light) is "royal blue", and the negative primary (paint, ink) is "sky" blue.

Children's paint sets regularly get this wrong...

Modern paints use magenta for "red" and Cyan for "blue". So it's literally just inverted RGB, using the secondary colors instead of the primary (of course, language is malleable and so they just call those the primary colors in paint... But it's the secondary colors of RGB).
