So to summarize, there is a two-layered lookup going on:
* In the paint file itself, after the true header, before the
vertex:paint-index lookup, there's a paint-index to paint-name lookup,
e.g.:
1 SUL
2 GYRAL
3 SUL.CeS
4 SUL.SF
* In the area color file, there is a lookup from paint-name to color, e.g.:
SUL 125 125 125
GYRAL 255 255 255
SUL.CeS 0 255 255
SUL.SF 0 125 255
Sounds like you've got it figured out, but for others' benefit...
