Pixel Spy is a simple utility which allows you to determine the magnitude of the various color components which make up a color on the screen. Specifically, you can select a pixel from the screen, and Pixel Spy will tell you the RGB, HSV, index and hex code values for the color of that pixel. You may also modify these displayed codes to manually change the current color.
• What is it good for?
Its primary target is those of who who get frustrated trying to match a color on the screen. For instance, this would be useful if you are in Photoshop and you want to sample the color from a non-Photoshop window. Just open up Pixel Spy, examine the color of one of the pixels and enter the values into Photoshop's color picker. You can also do the same thing with any application that uses Apple's color picker.
It is also particularly useful for determining the color hex codes needed in HTML documents, as you can determine the code for a particular pixel as well as quickly try out different combinations you come up with by altering the values manually.
• How do I use it?
Usage is simple. Just open the application, point the cursor at a pixel on the screen (you'll see a magnified view of that region in Pixel Spy's display) and hit command-F. The selected color will be copied to the current color swatch and the color's values will be displayed in the various fields in the window, where you can transcribe them into whatever program you want.
You can also manually enter values into any of the fields to come up with your own color. As you enter the values, the displayed color and value fields will update themselves dynamically.
The current area display field can also be modified, by toggling the crosshairs or changing its magnification, via functions in the "Capture" menu.

• FAQs
What is this "Exception Thrown" error I get when I open a new window?
This is most likely caused by a lack of free memory. Try using just one spy window at a time, or increase the Pixel Spy's memory allocation in the Finder's Get Info window.
What is this "Small (255) Range" menu item?
Macintosh RGB and HSV colors typically range from 0 - 65535. Unfortunately, most programs use numbers in the range from 0 - 255 for these values. Having this menu item selected will cause those values to scale to this more more usable range automatically.
How can I stop my wood from splitting when I put a nail through it?
Try cutting the tip off of the nail with a good pair of wire cutters before your nail it in. The pointed head on the nail acts like a wedge, forcing the woody material apart. Cutting the tip off prevents this from happenening.
Why is my computer slow with Pixel Spy open in the background?
On older computers, having Pixel Spy's window continuously track where the mouse is may degrade your performance. Try pausing Pixel Spy's scanning (using the button or menu item) when it is in the background.
