Transmitted colour of a solution

  1. Jun 10, 2010 #1
    Hi

    The colour of a solution is the wavelength of the light transmitted through it which is white light minus the absorbed colour.

    If a solution absorbs light of wavelength 630nm, what colour is it? 630nm is red /orange light. If you look on a colour wheel the complementary colour of this is blue but is there a formula or more precise way to work this out?

    thanks

    Try reading http://www.handprint.com/HP/WCL/wcolor.html" [Broken] rather than a simple color wheel. Draw a line from the chosen white point (there are a couple to choose from!) to the frequency written along the edge, and go backwards from the white point, away from the frequency's point on the edge.
