# Get RGB value from a Color Wheel [closed]

Say I have a color wheel like this http://bluelobsterart.com/wordpress/wp-content/uploads/2009/03/rgb-color-wheel-sm.jpg

Now how do I determine the RGB value at one particular point inside the circle.

 Sorry! I thought color relates to visible light, hence the post. Wont happen again. – SatheeshJM Jun 19 '12 at 22:13 It does, but not everything about color (or visible light) is on topic here. If you're asking about color as it relates to the frequency of light, then you're probably fine, but RGB values have to do with the digital representation of color, so they're not for this site. It's possible that this might fit on Graphic Design, but I'm not sure - I'll check with someone from that site and see if they can offer any input. (Also, don't worry too much about your question getting closed - it's natural for this to happen when you're not sure of the site's scope, so we don't hold it against you.) – David Zaslavsky♦ Jun 20 '12 at 3:34 Hi Satheesh. I'm taking a bit of a guess as to the particulars of your question, but I think you are asking how to calculate the actual RGB values given the color of a particular pixel or point on an image. If so, this particular question probably wouldn't be a great fit on Graphic Design either but may be a better fit for the Stack Overflow (I see you have an account there already). If you have questions about the appropriate use of color in a design, please do ask us over at GD! – Farray Jun 20 '12 at 4:23 Thanks guys! I actually thought of posting on Stack Overflow, but saw a few users being banned for posting wrongly (something about gaining negative reputation).... Wasn't sure where to post.. Hence I came here... Never mind though... I figured it out.. :) – SatheeshJM Jun 20 '12 at 4:54
