Red and Blue would form purple - as you add more blue into the mixture the colour created would be a darker purple, you can also add TINY amounts of yellow to create a brown/purple outcome, too much yellow to the mix would create a dirty looking green.
Purple paint!
maybe you can paint it if the dog dosnt move their paw
Assuming you want to cover up the purple so you can start over: buy the type of paint that covers water stains, deep colors. Kilz makes a paint that does that. Then, paint over that with the color you do want.
Red is a primary color, meaning it cannot be created with a combination of any other color.
Blue and red together make purple. For a different shade of purple you can change the shades of blue and red or use more of one color than the other.
add a lot of white paint and you will have a lovely pale violet
if you paint it
add blue
Probably purple and white, watered down a bit if you're using paint.
I believe any color mixed with itself makes itself. So purple mixed with purple makes purple.
Orange i like the color orange and this question got me a a+
