Light Blue

Light .. blue?

Hmm .. What two colors make blue? Blue and white? Im not sure if thats right.

The answer will depend so you're the mixture of compounds (which seems like you are, your answer) or light. When you mix the colored compounds, like painting, then white and blue would achieve a lighter shade, depending on how much white you have added. Because color objects is determined by which the colors of the "rainbow" or they absorb the visible spectrum, and reflect. Then the blue paint is blue because it reflects the blue light waves that fall upon it, and absorbs all other wavelengths. (Already noticed that at night you do not notice many colored objects, or changed their colors appear - the illumination that occurs from artificial lights does not generally a full range of light waves.) If you are mixing light waves, then you need to understand that many colors are mixtures of three primary colors: red, green and blue, mixed in different proportions. White light is actually a combination of all wavelengths at once, so if you added this to the blue light, it would not make much difference unless your blue light was very low and was removed. Under the shade of light blue that you want you need to experiment to find the right mix. Or simply use a transparent blue film of the right tint to filter white light - a combination of these two approaches!
