I need help with color combinations!

[Zen]

It has to do with how the color is being made. The primary colors of LIGHT are red, blue, and green, which is why web colors are given in RGB code. So #005599 uses no red, 33 units (I forget how it's measured) of green, and 99 units of blue to create that light, slightly greenish blue. .

I learned about colors in photography. The visible spectrum of light is made up of all colors, going from longest to shortest is ROYGBIV(red,orange,yellow,green,blue,indigo,violet). This would be the same as Uforgot's experience in physics.
I think you use the additive principle when you use RGB

Now when it comes to printing photographs your assertion is correct, we learned it as a subtractive principle using cyan, yellow, and magenta filters.You see the same principle in adjusting color balance in Photoshop.

Therefore Mr.1150A,the best accent colors to use are up to the bike owner

Maybe you should get some swatches from the paint store.
