Identifying Colours – Review 7

When I look at the computer screen, I normally just consider the content. Does it really matter whether something is light grey or dark grey?

To professional creators (e.g. artists, filmmakers, designers, and programmers), the precise colour displayed can be a very important consideration. Even a non-technical user might want to make sure their pictures and captions are the same shade.


Hexdecimal Logo

Hexdecimal (spelled differently from ‘Hexadecimal‘) is a nice little ‘eyedropper’ tool to determine what colours are shown on your screen.

When opened, it shows a customizable window with a palette, two trios of color sliders, a list of text boxes, and a status bar.

The text boxes on the right side display the current colour in six different formats:

  • CSS-friendly
  • Hexadecimal (uppercase)
  • Hexadecimal (lowercase)
  • Red, Green, and Blue levels in decimal
  • CMYK (useful for printing)
  • Common name

Click on one of them to copy the displayed text.

If you have recently copied something that Hexdecimal understands as a colour, then the ‘Paste’ button will be enabled. Click the button to display information about that colour.

What if you want to know more about an actual colour that you see on the screen? Left-click once on the large coloured rectangle in the middle of the window, then move the mouse so it’s pointing at the desired item. Holding down the left-mouse button will let you scan multiple on-screen colours. The program will only pick up a new colour when the mouse is motionless.

By default, the Hexdecimal window will remain on top of all other windows. Click the pin icon to toggle this setting.

If the program doesn’t quite work as you need, there is a helpful ‘readme.txt’ file bundled along. It includes full explanations for each of the multiple settings Hexdecimal understands.

All in all, Hexdecimal is a very nice tool. There are many competitors which offer eyedropper functionality, but I feel that Hexdecimal can easily hold its own.
