Would the penumbra spell (0 level wiz) prevent penalties from glitterdust?
Thoughts:
-The spell specifically says it prevents blindness and penalties from bright lights (including blindness).
- It's a darkness effect (thus would lower "nonmagical" light effects)
- Glitterdust is NOT a light effect, so there's no argument to be made from being a higher level spell. (Likewise, faerie fire (L1) negates displacement (L3) so lower levels spells are known to block higher level ones).
- Glitterdust specifically causes a penalty to stealth and potential blindness, based on the glowing (sparkle) dust- specifically effects that penumbra claims to prevent.
Am I missing anything?

The target of this spell does not suffer any penalties or blindness caused by bright light, such as those from light sensitivity or light blindness.
School conjuration (creation);
Components V, S, M (ground mica)
Bolding mine.
Penumbra specifically protects against bright light induced blindess. Glitterdust is a literal handful of glitter you whip at someone and use magic to make more of. It's not a light spell and it'd be hard to argue the sparkle causes the blindness (otherwise everyone who looks at the glitterbomb would need to save too). It's just a fancy version of whipping sand in someone's eye.

Glitterdust does not say it blinds by light, golden particles carry the blinding effect which cannot be avoided... they also sparkle. Clearly glitter makes everything better! *-<8^) *:・゚✧* ・゚✧ *
A cloud of golden particles covers everyone and everything in the area, causing creatures to become blinded and visibly outlining invisible things for the duration of the spell. All within the area are covered by the dust, which cannot be removed and continues to sparkle until it fades. Each round at the end of their turn blinded creatures may attempt new saving throws to end the blindness effect.
Any creature covered by the dust takes a –40 penalty on Stealth checks.
I'd agree with Bob in that Light spells are Evocations, Pyrotechnics(blinding light) & Fear the Sun(light blindness penalty) are Transmutation, while Glitterdust & Dust of Twilight are Conjuration.
