Need the RGB number for a color? If, for example, you're writing or editing HTML code, having quick access to color codes can be a great help. ColorPad is a feature-rich yet tiny color picker for Windows that can do the job for you.
On execution, you'll see the small, odd-looking ColorPad window on your desktop. Alongside the program itself is a readme file that you'll need to read because using ColorPad isn't that intuitive from the get-go, although it does become eventually become very easy to use.
Left-click and hold the ColorPad window, then it will show any color you hover over on your screen. There is no toolbar either on the ColorPad window itself or on the tab on the Windows toolbar. However, simply right-clicking on ColorPad will let you into the settings and tools.
In Tools, you'll find options to change the color code type - Hex, Dec or Floating format - as well as a zoom mode and split-screen function. Settings options allow you to change the way the app behaves. For instance, you can have it sitting 'always on top' of other windows if necessary. Being so lightweight, ColorPad is ideal as a portable app on your USB drive too.
While it color picks perfectly well, ColorPad really isn't very attractive, but the developer has included a download on extra skins in the 'ColorPad skinning' doc included in the download.
ColorPad is a great functional and lightweight color picking app.
