Red is a primary color, you can't mix 2 to get red. Blue is primary, too, and so is yellow. You can mix any of the above colors to make another color. ie: red and yellow make orange. red and blue make purple. blue and yellow make green. yellow and green make light green. white and red make pink.
There are quite some differences between an optical mouse and a laser mouse. One of the most noticeable differences is the type of rays coming out of the mouse. Now,we all kâ¦now that from an optical mouse there is (usually) a red light coming out and on the other hand, the laser mouse does not produce such light.
Invented by Douglas Engelbart in 1963, the mouse is a pointing device that recognizes two-dimensional motion. It is found on just about any computer that has a keyboard and commonly used to navigate graphical interfaces. The mouse did not become popular until 1984 when Apple integrated it into its famous Macintosh computer. Peripherals
