+OxygenEnhanced is a +1Multisized X11 Mouse Theme; +1Multisized is my concept for cursor themes with colorful pointers or pointer with colored backgrounds, and is accomplished by defining the colors that we will use in our cursor theme and set the initial size of the cursor, increasing one pixel between each of the colors. This is my original idea.
For this X11 mouse theme, I defined six colors for pointers, and the initial cursor size is 32 pixels. Therefore we have cursors of Green 32, Yellow 33, Red 34, Blue 35, Aqua 36 and Fuchsia 37 pixels. There is a 5-pixel difference between the initial size and the final size of the cursor . Simply imperceptible difference, and will be less if we choose 4 colors, or a larger initial size of the cursor.
