iphone上的蓝色字体

Anyway, you may know this, but in case you didn't (paging Captain Obvious), in the /Applications/Utilities/ folder on your Mac, there is a program called DigitalColor Meter, and it will give you the color value for any pixel on the screen. I used this to grab the correct RGB values from the Contacts application running in the simulator, which showed the RGB values for that blue color is:
Red:   0.243
Green: 0.306
Blue:  0.435
or if you prefer it in 8-bit designation:
Red:    81
Green: 102
Blue:  145
If you want to add this method to the More Colors Category I posted a few months back, the method would look like this:

+(id)tableCellNonEditableTextColor {vendColor(81, 102, 145);}

Or, you can just create it like this:

UIColor *thatTableTextColor = [UIColor colorWithRed:0.243 green:0.306 blue:0.435 alpha:1.0];
