hyperion.ng/effects/mood-blobs.py
Fabian Hertwig 2b3a3be0d3 Added the possibility to change the base color of the mood blobs over time.
The base Color is moved 1 degree in baseColorChangeRate seconds if activated.
It is moved between baseColorRangeLeft and baseColorRangeRight. These Values are in degrees. When these borders are set to the full circle (eg. 0 and 360), the base color moves around the colorwheel, otherwise it moves from left to right and back again.
Furthermore there are three effects script for this feature: "Full color mood blobs" which moves around the full circle, "Warm mood blobs" and "Cold mood blobs" which only shows the warm, cold colors.
This update wont change the functionality of the old scripts.
