Reimplement the colour guide so that it does not use colour and/or fill scales

Reimplement the colour guide so that it does not use colour and/or fill scales. The current use of these scales blocks the use of these aesthetics for other purposes in the same plot, creating a surprising limitation.
Hardcode the wavelength to colour conversion in an annotation-like geom (e.g. similar to geom_hline() and explore if the support for colour gradients in recent versions of 'grid' can help improve performance and/or smoothness.

Include support for a transformation on wavelength values to create "false colour" scales.
