If you need something immediately and just need a darker color you can use:
- ABS (black in color but only available in 1.5" and 2") MUST use ABS glue, not PVC glue
- Electrical PVC (sch. 40 and light grey in color) sweeps available but limited on fittings
- Schedule 80 PVC. Dark grey color - many fittings available but about 4x cost of sch. 40
I have a ton of BLACK Flex PVC pipe in stock here in Garden Grove in all sizes (but no black fittings)
I also have a crap load of Sch. 80 fittings.
As for Sch. 40 (white) I've got more than HD and Lowes combined (yea, I wish I were exaggerating)
