RainbowGround is a utility for background images creation.

It produces periodic, tileable images based on user-given or randomly generated color factors values.

RainbowGround can save resulting images as Web background (*.jpg)
and as Windows background (*.bmp)

At the upper left corner of the RainbowGround window there is preview area of generated image.

Sliders around it are controlling red, green and blue color factors. As you change their positions, resulting image is changing too.

· Single-window, easy-to-use interface;
· 32x32, 72x72 or 144x144 pixels images creation;
