NSColorCalculator has a custom Color Panel for working with colors thatʼs designed to be easy to use, intuitive, yet very powerful with the features you need to get things done fast. In a nut, itʼs a revolutionary way to choose and compare colors.
For instance, any Cocoa or iOS developer is all too familiar with certain mind- numbingly tedious tasks that have to be repeated over and over again. One of these is the dreaded: Find a color in a graphics app using its color picker panel, and then manually typing in (or copy and pasting) the numbers for each of the 4 components of RGBA or HSBA colors. Thatʼs the least painful scenario. Some of these graphics apps only have color numbers in 0-255 format, which is useless in Cocoa/iOS, so you have to manually divide the color values by the appropriate amount. In short, this is a giant PITA sandwich.
NSColorCalculator feels your pain and is here to help. With one mouseClick or menuItem selection, you can copy any color in native NSColor or UIColor code, in RGBA or HSBA format, which you can then paste into Xcode.
Of course, this app isnʼt just for developers. Artists and graphic designers will love all the options for choosing and comparing colors including the Shade tech and Component Locking that are completely unique to this app. Plus you can grab the color under the mouse from any app or anywhere onscreen by holding down the Control key.
