A colorful field region

> A transparent rectangular field entity that shifts its hue from one color to another (maybe through any amount of colors separated by commas??) in a loop (like the rainbow spinners). If you put multiple entities near other another they'll form a single field that shifts through the colors. The transparency of the entities, the colors and the direction of the color change (position mode like in camera triggers (maybe diagonal variants too? or just letting you set the angle)) are customizable.
