FO can darken the base if there is vanilla in it, but that will take time, maybe few days?
It starts on the outside of the bars and spreads towards the middle. It doesn't really look like that's the case with your soaps.
And also if the FO is quite yellow, like few that I've used in the past, that will make the base somewhat tan or yellow.
Gel will make the colour pop and make it more bright, same with the uncoloured base. It might look a bit darker in comparison to non-gelled one.
I've never used EVOO but, I guess it it's quite dark green. That might be the issue there with your recipe. You can also try and replace some of the EVOO or OO with Rice bran oil.
Even though it is darker in colour, it doesn't affect the colour of finishing soap that much. It's lather is great and it gives nice sheen to the finished bars.
Ok I will use this EVOO for dh's castile. He doesn't care what colour his soap is and if I add honey it does golden anyway. Thank you and Obsidian, for that advice.
I made a soap with 60% RB (mine is really golden! not green at all) and it is still only 10 days old so probably silly to worry about it but it is difficult to wash it off. It is nice once you do get it off. I will wait for it to cure more, I just panicked and went back to OO and now look what I've done.
This soap making is incredibly difficult.
I made 2 lots yesterday. Exactly the same recipe and method.
Mix 1 (Almond oil 10% and BB winter gardenia FO this is clear OOB)has hardened and I have cut it. Bright yellow but a good soap.
Mix 2 (Camellia oil 10% and BB champagne FO this is a bit yellow OOB) is spongy and way off cutting. I put 2 drops (seriously) of green colour in the base. It's a dark dirty olive green colour.
I have used both Almond and Camellia oil before and they were fine.
Do you know what have I done to this second mix to make it so spongy?
