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.
The mouse then sends this movement data to your computer as mouse input, and the computer moves the cursor across your screen. Laser mice function similarly, but use infrared light instead of visible light. DPI Explained. Dots per inch (DPI) is a measurement of how sensitive a mouse is. The higher a mouseâs DPI, the farther the cursor on your screen will move when you move the mouse. A mouse with a higher DPI setting detects and reacts to smaller movements. A higher DPI isnât always better. You donât want your mouse cursor to fly all the way across the screen when you move your mouse a little bit.
