Hue = basic color. Saturation = how much of the "pigment" of that color is. With no saturation, it's a grey tone of that color.
Luminosity = Lightness of the color on a scale of black to white with the color's tones in between. This is the oddest of the bunch since how the computer represents it isn't really possible with paint pigments (additive vs. subtractive color mixing). But a way to think of it is to take the color as base and then mix black in to get it darker and darker until you hit pure black and the opposite with white. One of the problems for most people with computer color picking is that we're used to thinking of subtractive color mixing. Or you can think of it as reflected. We mix paint/ink pigments and put them on paper. Light hits the paper and reflects back at us but has had some of the wavelengths absorbed by the pigments thus subtracting them out of the mix. If you mix all the pigments together, you get black because you are subtracting all the wavelengths of visible light. The other approach is additive color mixing. Additive is when the visible spectrum "primaries" of Red, Green, and Blue are mixed together they create white. Since monitors use this method, the approach to color mixing is a little off of what most people are familiar with from school with paints. But it's an approach that many photographers understand because they use additive light filtering for color film development. http://www.normankoren.com/light_color.html -Kevin On 7/5/05, Ian Skinner <[EMAIL PROTECTED]> wrote: > So not the real question; what is "Hue," "Saturation," and "Luminosity" and > how do they effect a color in layman's terms? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Find out how CFTicket can increase your company's customer support efficiency by 100% http://www.houseoffusion.com/banners/view.cfm?bannerid=49 Message: http://www.houseoffusion.com/lists.cfm/link=i:5:162982 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/5 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:5 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.5 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
