I am new Mac user and I don't really like the Magic Mouse so I reverted to a good old 3 button mouse with a scroll wheel. When I turn the wheel slowly, it only scrolls pixel per pixel (or per two pixels) If I turn the wheel more quickly, it scrolls nearly line by line. To install the Pixel Bender Toolkit in Mac OS: 1. Download the Pixel Bender Toolkit DMG file. Double-click on the DMG item to mount the installer virtual disk. In that virtual disk, double-click to launch the Setup application. The Pixel Bender Toolkit files are installed into your Applications folder under.

First, They Set Fire to Stone
Miners set fire to stone in the Hindukusch six score years ago. Then, cold water was thrown after the flames.
The sudden cooling cracked open the rock and stone, of course, and brought to light a much sought-after gem: in the 1880s, sky-bluelapis lazuli pigments were mined using the 'fire-set' method.
Want to know the RGB values of that skyish blue on your Mac's screen? You need neither throw fire at it nor high water; follow these steps instead to crack the coloring code:
How to Use the Eyedropper on a Mac to Identify the Color of Any Pixel on Screen
Time needed: 5 minutes.
To find the color value (in RGB) of any pixel on your screen using the macOS Digital Color Meter (Mac eyedropper tool):
- Open Digital Color Meter.
Tip: You can find Digital Color Meter using Spotlight search as well as using Launchpad, of course, or open the Utilities folder in Finder.
- Turn down the Aperture Size to its very smallest (on the left).
Note: This will allow you to see the color value of a single pixel; with an aperture bigger than this, you will get an average value of all the pixels in the selection square.
- Position the mouse cursor exactly over the pixel for which you want to identify the color.
- Optionally, press CommandL to lock the picker on the currently selected pixel or pixels.
Note: You can also press CommandX to individually lock the horizontal dimension and CommandY to lock the vertical dimension respectively.
- See the RGB color values listed under RGB.
Tip: You need not copy the values by typing.
Press CommandShiftC to copy the color values as a triplet of plain text numbers.
Press CommandOptionC to copy a 74⨉74 square filled solid with the color; you can paste it into a graphics program, for instance, or just into Notes.

What do the RGB values mean?
The RGB values are the amounts of red (R), green (G) and blue (B) that combined make up the measured color. The values are from 0 (lowest) to 255 (highest).
A RGB value is relative to a color space.

Can I choose a different color space for the values?
Yes. Select the desired color space in the Digital Color Meter's drop-down menu; choices include various standard RGB color spaces as well as the human-eye L*a*b color space.
What is a color space?
A color space contains all the colors a specific device can produce and a method to express them. Specifying the color space together with the RGB values lets you reproduce the same color accurately across devices.
Choose a color space that the device where you want to use the color supports.
Mac Os Mojave
What is the L*a*b color space?
The L*a*b color space contains all the colors the human eye can see. Instead of using red, green and blue, L*a*b defines colors as brightness (0–100) — L — , colors from red (-128) to green (127) — a — and colors from blue (-128) to yellow (127) — b.
Can I convert the color values to CMYK, XYZ, HSL and other color spaces?
Yes, though Digital Color Meter itself will not do that for you.
Turn to a site like Colorizer to enter the values gained from Digital Color Meter and have them converted to the color space and specification you need.
