A picture would help if possible, but sounds like DOS which is the oils going rancid. Are they starting to develop a funky smell?

A picture would help, DOS tends to start out an ornagey color in the shape of a spot.

Also what was your recipe? Some oils are more prone to DOS then others. A pic and the recipe might help us diagnose.

D.O.S stands for dreaded orange spots. When it happens means oil has gone rancid in the soap olive oil sometimes tends to have issue . The Veg oil depending on whats in it could have issue also. Is there a funky smell ?

You can have dos without a smell. It's not exactly the same as when the oil goes rancid.

The greater the unsaturation, and especially with polyunsaturates (that were likely prevalent in your "veg oil"), the more prone to this reaction. In use it makes practically no difference, it'll just look funny.
