Composite aircraft parts are painted light colors so that the core material (most often foam) does not exceed temperature limitations (in addition to fiberglass and epoxy getting to hot). The foam core is the part that will melt from high heat.
What is the core material of your composite canopy? What is the temperature limitation of that material?
