Portable ColPick

ColPick is a feather-light and portable color picker that captures the HTML hex string of any color from the screen, along with its RGB values. It has a couple of intuitive options that can be tackled with ease by all types of users.

Simple GUI for grabbing colors

The interface is represented by a very small window with a straightforward look, where you can click and drag a square to any part of the desktop to grab the current color while previewing it in an area of the main frame.

View HTML and RGB color codes

The RGB channels and HTML color codes are automatically calculated and displayed. The HTML string can be copied to the Clipboard by simply clicking on it. However, there are no similar options implemented for copying the RGB numerical values, so you have to manually take notes in a text editor.
Apart from the fact that you can make this frame stay on top of any other windows, there are no other notable settings available.

Portability advantages

The entire program's wrapped in a single .exe file that can be copied to the hard drive or to a removable storage unit to directly launch ColPick on any PC without previous setup. It doesn't need DLLs or other components to run, create files on the HDD without permission, or integrate new entries into your system registry.

Evaluation and conclusion

It didn't put a strain on the machine's performance in our tests, running on low CPU and RAM. No error dialogs popped up and it didn't hang or crash.
However, it had a slight delay between pointing the cursor to a color and displaying it in the preview area. On top of that, the preview area is too small and there are no options for copying the RGB color codes. We are also keeping in mind that ColPick hasn't received updates for a long time.
