Bought from the dealer. AC Delco. Concentrate is orange-ish. After I mix it with distilled water, it is pink to the eye. Not irridescent pink like some other brands, but still pink.

Since you are so good at googling, goole "pink dexcool or dex-cool" and get the answer. Lots of pink Dex-Cool.

Here is a start for you. Looks pink to me.

WTF? H₂O wont alter a color.

 

Of course it can.

 

I use H₂O to thin paint, NEVER changes color!
You need schooling:
Mix white into orange until it creates peach then then add a few drops of red. Then a bit more white it will in turn create a tint with a pink hue. Red and white will create pink.



Primary Colors: Red, yellow and blue.
In traditional color theory (used in paint and pigments), primary colors are the 3 pigment colors that cannot be mixed or formed by any combination of other colors. All other colors are derived from these 3 hues.

Secondary Colors: Green, orange and purple.
These are the colors formed by mixing the primary colors.

Tertiary Colors: Yellow-orange, red-orange, red-purple, blue-purple, blue-green & yellow-green.
