no
A garnet is a red stone and it will not turn pink in the sunlight.
grey, or black or brown
1 and 1/12 of a can of paint
By mixing red and white together.
red is a primary color so no colors make up red if that is what you mean Red is NOT a primary color of pigments. They used to think it was. But your color printer on your computer makes red by mixing magenta and yellow. You can do that with paint too. I wish schoolteachers would stop teaching the old color theory. It's wrong. The true primaries have been known for over 50 years, but too many people want the old primaries taught because "the masters" used them.
Pink is not a primary color, therefore it cannot turn into the color red.
Pigment is the color added to paint. Green paint has green pigment, red paint red pigment, and so on. Many paints will have a blend of different colored pigments to get a precise color, such as red and white to get pink.
The color is red but it does look pink. I believe the exact color is Primary red, I'm saying this because it reminds me of the red paint I have. I hope this helps.
black
Depends on how much paint you want, If you want 11 gallons, three gallons of red are needed. If you have two gallons of white paint, you'll need three quarts of red paint. Take however much you need to do the job, divide that amount by 11, multiply that total by three and that will tell you how much red paint you need.
