> There is still Color::Rgb on CPAN (note the spelling).

When I noticed modules were missing from doing 

perlbrew clone-modules perl-5.38.2 perl-5.42.0
I put the results of list-modules for both versions into respective text files and ran diff. Perlbrew listed the Color::Rgb in 5.38 as Color::RGB which caused clone-modules to fail for that module. I just tried to install Color::RGB manually on 5.42 and it failed of course. So I installed Color::Rgb into 5.42 and ran list-modules again and sure enough perlbrew reports that module as Color::RGB! When I went to CPAN and saw 
Color::Rgb - Simple rgb.txt parsing class
Color::RGB::Util - Utilities related to RGB colors
I didn't know what to think, maybe it got renamed? But I checked out the changes and it did not so I don't know what is going on with perlbrew. Try it yourself: 
% cpanm -v Color::Rgb
% perlbrew list-modules | grep -i 'color::rgb'
Color::RGB
