Add 3-colour, tri-color or RGB example combing 3 wavelengths in one image/plot

[samaloney]

Describe the feature

Combing multi-wavelength images on a single plot is a really useful analysis tool and one way to do this is to make use of the the three RGB channels for three different wavelengths image. For example like this plot created by @Shilpi96
using code from @eoincarley

Proposed solution

Create an example showing how to to create such tri-color or RBG images combing 3 different wavelengths using sunpy Maps

[Shilpi96]

yes, this would be very useful. I would like to add an example.

One possible way of doing this is with the make_lupton_rgb function in astropy (e.g. this gist https://gist.github.com/wtbarnes/62ef2995369a17eead6c3ce331985cd0).

I think this is a good idea. I wonder if it would be better suited for the sunkit-image gallery.

An example using make_lupton_rgb() was already added in #6459 (and then moved to the sunkit-image gallery in sunpy/sunkit-image#128). Something similar can also be achieved using mplcairo (see #6835).

Closing this issue as completed
