Brilliance was a paint package for the
Commodore Amiga. It actually incorporated two separate programs, "Brilliance" for register-based graphics, and "TrueBrilliance", allowing 15 or 24-bit
true-colour graphics.
TrueBrilliance was notable in particular, because it allowed users of ordinary Amigas to create true 24-bit colour images whilst
rendering them as
HAM6 (on older Amigas) or
HAM8 (on
AGA-equipped machines). TrueBrilliance was generally held to be a better
HAM-based paint program than the relatively slow
Deluxe Paint IV.
Early versions came with a
dongle, and were fairly expensive. Brilliance 2.0 (actually not that big an upgrade) dispensed with the dongle, and was much more affordable.
Sadly, Brilliance probably came out too late in Amiga history to achieve the same level of recognition that
Deluxe Paint did.
