The first workers are in deed smaller, all workers are a little pale when they just hatched. It could take a few days until they are fully colored.
It takes up from 4-8 weeks to hatch from egg to larva, but like you said depending on the species and temperature, humidity, food, etc...
Also, when the colony is small the workers only come out at night to feed, they feel saver at night.
