Tested out new colours (Holbein's W049 and W139) on 100% pulp (Holbein's Albireo) as undercoats, and...
They stayed!
Even after billion brushstrokes over them!
\(^o^)/
Cheers to the manufacturer for indicating staining powers in catalogue.
Next time try:
- pen more, so colours need less brain
- put yellow first, then brown over
- after undercoat (setting where to leave white), paint darkest colour to use as contrast ceiling
- stop relying on coupy pencils
- stop relying on coupy pencils
- ...but they will always be here...
