So blue and yellow make grey?

[Overthemoon]

I just made my first batch after my lye burn (hand still looks gross and it's going to have craters but no nerve damage was done so I'm good) and I mixed yellow and blue liquid concentrate since I've gotten a beautiful deep green doing this before. Wouldn't you know this time it is a LIGHT grey. How does castile do this? I do not know.

Anyone have any ideas. I used the same amount of colourant I have before although I used a different oil blend last time. Just... Grey? What the heck?

Well you've got to take into account the colour of the soap before adding the colours, and that all depends on the oils you are using. For example a 100% coconut soap is going to be white, while a 100% Olive oil soap will be a murky yellow or green depending on the oils.

 

[Overthemoon]

Yes, with the yellow or green of castile I would have expected a different shade of green. It's the very light grey that has thrown me off. It looks more like a coconut base because it is so light. I know better but it still has me boggled.

I can't make any promises but give it a few days... it may surprise you and turn green... or greener.

I recently made a batch of lavender scented soap and colored with a combo of ultramarine pink and blue. When I put it in the mold it was a weird dark gray... when I unmolded it looked like processed lunch meat (kinda ugly pink/grey with white spots). I just looked and it is now almost the pretty lilac color I was going for... though a bit darker than I wanted.

well, I added purple colorant to yellowish soap (from the EOs) and ended up with gray, so I'm not terribly surprised.

(yes, pH stable colorant)

I was reading in the Soapmakers Companion earlier this evening and it seems the PH in the soap from what I am understanding, makes it have different colors. I was reading in the natural coloring soaps area about the alkanet root and it said that it colors an acid vegetable oil with a PH of 6, red, a somewhat alkaline soap mixtire with a PH of 8 shades of lavender, and a more alkaline soap mixture with a PH of 10 a shade of blue.
So does this mean different oils also have different PH? Because she says in this same area to use the root to whichever oil is unsaturated, is most predominant in the formula. So it got me to thinking just wondering about the PH in the soaps and how this makes the color it is.
I am new at this so I might be in left field here. lol

Also, did you put color in before or after you put scent in?

 

[Overthemoon]

I put the colour in after the scent. It's turned a little tan/ purple-ish colour now. I'm going to chock this up to colour warping and wait and see how it develops.

Hi Overthemoon:


I suggest Rosehip Oil (Rose Mosqueta) for your hands. There is a lot about this oil on the internet. It is praised for its effect on scars.

I used it for a long time for acne scars.

Warmest regards and take care

Same thing just happened to me!

This is the first real morph I've had. I really wouldn't expect Castile to be so... Not green or yellow but it still feels nice so I won't complain too much.

I have learned one thing thanks to the batch after this... Jojoba meal makes dark brown, near black soap. It looks like chocolate but it smells like nag champa.
