Put the white down first and add the color little by little: that way you control how light it gets.
For a pastel shade, use lots of white and very little color.

What color do blue and white make?

Blue + white, in equal parts, make sky blue. With more blue it leans toward cornflower blue, and with more white, toward pale blue.

What ratio of blue and white should I use?

Half and half makes sky blue. 2 parts blue to 1 part white gives cornflower blue; 1 part blue to 2 parts white gives pale blue.

How do I make sky blue lighter or darker?

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

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.
