This may just be me, but I think the feat is underpowered. A feat in Complete Arcane, called Collegiate Wizard (chooseable only at first level) gives Wizards +2 to Knowledge (Arcana), and doubles the spells they gain for free and and at first level. Now, I'm fully aware that we're not allowed to use things from non-core books here, so I'd suggest an alternate benefit. As a few examples...
A special list of unique spells only available to graduates of the Chromatic Order becomes available... I could spin out half-a-dozen on short notice.
A special ability to craft minor magical items (anything with a market value of 1000 Gp or less) is granted.
A bonus to spells/day is granted... an extra two cantrips, perhaps.
