Ok, I really suck at figuring out how to make math give me the answers I need, and have come to a point where I have a problem that only math can solve, but haven't the slightest idea how to do it. So for those of you who get off on pushing numbers around, this thread's for you.
Think of it as a story problem.
Justin has received from a client a Photoshop image that uses the RGB color space. The color of each pixel in the image is a combination of (R)ed, (G)reen, and (B)lue. In PhotoShop, each of these three primary color values can be defined in a range of 0-255. So to define any color, PhotoShop uses R=0-255, G=0-255, B=0-255.
Now, the Photoshop image is nothing more than a storyboard concept for an animation Justin has to create in SoftImage XSI, a 3d program.
XSI, being made by the contemptibly obstinate French uses a different numbering system for the values of RGB. Instead of ranging from 0-255 for each of the three primary colors, they use a decimal range of 0.000-1.000 So any given color can be defined in SoftImage using the following: R=0.000-1., G=0.000-1., B=0.000-1.000
Now, this particular client is very persnickety about details, and it's important that Justin get this color spot-on in his animation. How can he convert the PhotoShop color values of Red=0, Green=103, and Blue=143 to a decimal somewhere between 0.000 and 1.000 for each of these three color values?
