This definitely have some potential. 

Hi, 

This is definitely a great addition to the existing color Selector. Especially the fact that you are able to select colors anywhere on the screen.

Ah, I never noticed the PDE has a color selector!
Judging from the screenshots, this tool could be as well a standalone product. Perhaps you should add buttons to paste the selected color into the current caret position in the PDE. So we can write color(|), launch the tool, and get color(#CC2B99). Faster and less fuss than using the clipboard.
Or even generate color-related code (color, fill, background, stroke, etc.).

i really like your tool, great work. im already using it.


my requests would be:

• a slider to set the alpha value of the color. although its not that hard to add the alpha by hand to a hex-color.
• if i try to choose a dark color in the colormixer, the cursor (cross) starts to jump somehow. the lower (darker) i get in the color box, the more it jumps.
  
• would be convenient, to change the rgb/hsb/hex values by hand too.

cheers, thomas

Really appreciate the suggestions. Will try to implement them soon and improve things further. And do report any bugs.

Thanks

CPU on my Mac goes nuts with this tool installed.  Don't have to have the Color Selector window open for it to be effected.  Just launching Processing with the tool installed has CPU at 120% (out of 200%), without the tool .4%.

Thank you jeff_g and thomas_diewald for reporting this issue. There indeed was a major bug in the on-screen color picker code which was increasing the CPU load. It has been fixed now. I've tested it on Win 7 and Win XP. Do update to v1.0.2 available here and let me know if there are still issue. Update is a MUST for previous users. Previous versions are now deprecated.

Nice!  That fixed the CPU issue.  Here are a couple minor cosmetic things to look at that surface on the Mac.

First image, note the offset of the color picker window.  It looks too low and off the the right.  The bottom and right get clipped.
Also note the text areas are not sufficiently long enough to display 3 numbers, clipping the first digit.



Second picture clicks the little pull up arrow to hide the palette, which hides the buttons but shows a clip of the top of the palette.

This tool had my Processing app running on 200% cpu without running any sketches.

Color Selector Plus has now been updated to version 2.0.0. This version has more bug fixes and now all the text fields(RGB, HSB and Hex value) are editable like Processing's original Color Selector. Mac OS X UI inconsistency has been improved as well. Try it out guys. Your suggestions/bug reports are welcome. :)

Hello

Is there a way to implement the screen color picker in my processing sketch?
I want to write a program that automatically grabs the color from different spots on my screen.

I achieved that by basically taking a screenshot of a square region of the screen centered about the mouse pointer. You can take a screen grab and the color selected by the mouse will be the center pixel of this image. This tool is open source. You can check out ZoomScreen.java which handles the color picking. The important method is getScreen() defined at this part of the code.

Cheers!

This tool has been updated for Processing 2.0b6. This version is no longer compatible with older versions of Processing.
