Which primary colors (blue, red, yellow) do i need to create pink color?

red and white will give you pink.

Impossible. You need a white to make pink.
Red +blue = purple
red + yellow = orange
blue + yellow = green

but white isn’t a prymary color, i just have the 3 of them.

I know, but what you are proposing is impossible. Pink is a lighter shade of red, just as grey is a lighter shade of black. In order to lighten a color, you need white.

i see that. but it is not possiable to have the pink that you want without white.

Clear? Do you have clear? Watery red will look pinkish.

Sadly you can’t create pink with primary colors in real life, even though combining all primary colors produce white when we’re talking about additive colors. Unfortunately real life uses subtractive colors. As such it is impossible. EmpressPixie has the best solution to use the materials you have, but it won’t look as good as it would if you could get your hands on white.

If you go to an art supply store and buy some powdered titanium dioxide, that plus red will give you your pink.

Go to an art supply store and ask for some Tartan Paint.

On second thought, although the titanium dioxide would give you the white you need for pink, it would kill the transparency of the gel : (

You can’t get the white without losing transparency, I’m afraid.

I had an initial concern about how titanium dioxide would burn and if it could be hazardous to inhale the fumes. My quick googling has shown that inhaling the dust, as with inhaling most dusts, is not a good idea. But I can’t find anything regarding the possible effects of burning it or breathing in the combusted vapors.

Good thinking, but TiO2 doesn’t do anything in combustion situations. You’d end up with a smear of TiO2 (completely non-toxic) down at the bottom of the candle container once the wax had burned off

I’m not sure about that “completely non toxic” point though, since here in Canada TiO2 is classified as a possible carcinogen, albeit after years of being listed as not, and was only proven with rats at a certain high level of particles in air. So very unlikely to have any actual damage unless you apply spraypaint and breathe paint fumes for a living. And I admit that I’m nowhere close to a chemical scientist.

Ooh! Here’s an idea—
It’s common to put glitter in gel candles to add sparkle; why not just mix pink glitter into the clear (uncolored) wax? Pink + sparkle = win

do you know what glitter is, 2late2be?

use white-out and red

It is actually impossible because Pink isn’t a real color at all. It has no wave length and doesn’t physically exist. It is simply a figment of your imaginations.

Dude. You’re making gel candles.
Just put in less of the red stuff.
The gel base is clear, right?

@ nimis my thoughts exactly, though I have never made candles soo…
