Enhancement Request: Support both Blue and Cyan

[Kerrick]

For context, I'm trying to use these colors in my terminal for the basic ANSI 8-colors. This theme's Purple fills in well for ANSI Magenta, but this theme's Blue is not enough to cover both ANSI Blue and ANSI Cyan. I think it looks great as ANSI Cyan, but I would like to differentiate ANSI Cyan elements from ANSI Blue elements in Terminal User Interfaces (TUIs) I use.

I'm not good enough with color theory to pick a good blue color (for each of light & dark modes) that would differentiate well from this theme's Purple and this theme's Blue, maintain contrast standards, and look aeshetically harmonious with the rest of the colors. Is there any chance a second blue/cyan color could be added to this theme? If not, is there any chance you can leave a comment with your picks?
