CGContextSetRGBStrokeColor Chart?

[marshusensei]

Is there some kind of chart that gives the codes for Colors in RGB? in the format 1.0, 0.0, 1.0, 1.0

Thanks, this may be a very silly question.

You mean instead of the usual 255 format?

I bet somebody has created such a chart somewhere on the internet.

In the meantime, the UIKit has a number of "standard colors as UIColors:

[UIColor blueColor];
[UIColor redColor];

Here's the list of predefined colors from the Xcode docs

+ blackColor
+ darkGrayColor
+ lightGrayColor
+ whiteColor
+ grayColor
+ redColor
+ greenColor
+ blueColor
+ cyanColor
+ yellowColor
+ magentaColor
+ orangeColor
+ purpleColor
+ brownColor
+ clearColor


and you can get the CGColor for a UIColor like this:

[[UIColor blueColor] CGColor];

You could also ask the standard UIKit colors for their R/G/B values using the method getRed:green:blue:alpha:

It would take about 5 minutes to write a program that would put all the standard colors into an array, then interrogate the R/G/B values of each color and write them to the console log.
