How about a spectral camera that costs as much as an RGB sensitive camera?

https://en.wikipedia.org/wiki/Spectral_sensitivity

Covering the full visual spectrum?

https://en.wikipedia.org/wiki/Visible_spectrum

About 25 years ago when I used spectral devices I used ...

a 1nm visual range spectroradiometer costing around $250K

a 10nm visual range spectrophotometer costing around $10K

Might not be worth it without spectral monitors and/or spectral output
devices.
