Perhaps not everyone knows that DigitalColor Meter is a utility included in Mac OS X; and is especially useful for graphics and web programmers, as to the possibility in seconds, to know by the coordinates of the mouse pointer, the values of a specific color we see on the screen.
1.) DigitalColor Meter is used to find the reference numbers of the colors of the screen. Use the buffer memory of the video card, which stores the RGB values of all pixels of the monitor displays a graph where he writes the RGB values of the pixels of the object and then the object is automatically displayed on the monitor, allowing you to user to copy them and use them in their applications or programs.
2.) DigitalColor Meter indicates the numbers of RGB pixels on which the cursor is positioned. The ” native ” mode to capture the color of the numbers on the cursor position is RGB. The drop down menu has four choices: 1) Show Values Originals 2) Show in sRGB 3) Show in generic RGB 4) Show in ADOBE RGB. The commands to use are, CMD + SHIFT + C to Copy the text color; CMD + ALT + C to copy the color as picture. Also you can choose to display values in decimal, hexadecimal, or percentage and display the coordinates of the mouse position.
3.) The operating system uses only 8 bits, so the best way is to set RGB As Actual Value, 8-bit if you want the values in decimal or RGB As Hex Value, 8-bit if you want the values in hex (useful for HTML). The opening should keep it to a minimum, so a single pixel is captured; CMD is the command to enlarge 1, CMD + 2, CMD + 4 or CMD + 8 (the numerical value is the value of zoom for example, CMD + 8 means the zoom set to 8x); more opening is larger and more pixels are captured, and the program will return the value of the average of the selected pixels ..
