PS CS2 default.
Basically you should go to the window where you can choose gradients, take the light rainbow one, put every color a little closer one to another, and put no opacity on the sides. IDK if I explained it well I'll make a screenshot when I open ps

Mhh I just understood you wanted the rainbow gradient itself >.< I'll upload it, no ps here though so you'll have to wait a little.
