What is the best possible way to pick a color from the image ?

What I need is that, when I move the cursor to any particular point in the image, Hex code of the color at the cursor should be displayed.

Is there any free utility for that?

Even if it is not an Image, say I am working on any windows application having various colors, Is there any way to pick the color ?

PicPick is nice:

It is an all-in-one program that provides full-featured screen capture tool, intuitive image editor, color picker, color palette, pixel ruler, protractor, crosshair and even whiteboard.

In Windows, there is an easier way that doesn't need any software.

  1. Capture the screen in an image file (use something like the Snipping Tool to grab the desired area)
  2. Open the file with MS Paint
  3. Use Paint's pick color and pick the color
  4. Press "Edit Colors" button
  5. You have the RGB values!

As far as I'm concerned, this is the best solution listed, since it is universal and doesn't require installing any new software. – Ochado Oct 19 '15 at 14:34

Slow and tedious. We just need a quick color picker... – Pere Jul 20 at 8:19

Instant Eyedropper is exactly what you were searching for.

How it works

  1. Move the mouse pointer to the Instant Eyedropper icon in the system tray.

  2. Press and hold the left mouse button and move the mouse pointer to the pixel whose color you want to identify.

  3. Release the mouse button.

That's it. The clipboard now contains the color code - in HTML format (or any other format that you have previously specified). It can be pasted and used in any text or HTML editor or the Color Picker tool of Photoshop.

It comes with all the options that I personally wanted of such tool.

  • Clipboard color pattern (Hex, and others)
  • Startup on system tray
  • No overhead or ads and it's free.

Perfect. Tiny, simple, and does the job. Thanks. – hajamie Apr 27 at 21:56

I like Colorzilla when using Firefox. Simply use the eyedropper to click anywhere within the web page, including images, and it returns the RGB and Hex code.

While Colorzilla is quite useful, this is not a solution when you want to pick a color "on any windows application having various colors". – Emile Bergeron Jun 29 '15 at 0:28
    
While agreeing with Kevin, if your color is in a webpage, no need for extension (it may make it faster if you have to do this multiple times), but I just hit F12 to open the debug console, click the top left corner to "Select Element" and point to it on the browser – Nick Dec 1 '15 at 2:02
    
this is good, as it doesn't need any software installation, just open your image in browser or drag and drop the image in browser – stom Jan 19 at 10:40

I use Pixlr on account of it being web-based, so quick and easy to use anywhere that supports Flash.

Features I liked about Just Color Picker:

  • It's free.
  • It's portable (no installation is needed).
  • Supports many color formats (HTML, RGB, HEX, HSB/HSV, HSL, CMYK and Delphi).
  • Has hotkey and autocopy options.

ColorPic is free windows app that works well for picking colors. They have a paid one as well but I find the freebie works for the simple stuff just fine.
