White models turning brown in post-curing

My first resin prints, fwiw.

White Peopoly resin, after 20 minutes in the curing station (peopoly’s curing light) the models are a beige-almost light brownish color.

Normal? Or am I doing it wrong?

how big is the model?
the brownish color indicates that you have cured for too long
for clear it would be yellowish but other colors does not seems to show color changing effects
leaving the model curing too long will make them becomes brittle

about 6"x1".

How long should I cure typically?

It’s best to check the print every 10-15 minutes
make sure that you placed the print in water under the curing LED, this can prevent over curing.
