Start with the lighter color and add the other one little by little: the darker one usually takes over.
Does it look dull or muddy? One of the two contains a bit of a third color. Try purer paints.

What color do pink and blue make?

Pink + blue, in equal parts, make periwinkle. With more pink it leans toward mauve, and with more blue, toward cornflower blue.

What ratio of pink and blue should I use?

Half and half makes periwinkle. 2 parts pink to 1 part blue gives mauve; 1 part pink to 2 parts blue gives cornflower blue.

How do I make periwinkle lighter or darker?

Add white little by little to lighten it (light periwinkle) or a little black to darken it (dark periwinkle).

Is it the same with watercolor, acrylic and oil?

The result is similar. Watercolor looks lighter because the white paper shows through; acrylic gets a little darker as it dries.
