QgsVectorColorRamp -> QgsColorRamp QgsVectorGradientColorRamp -> QgsGradientColorRamp QgsRandomColors -> QgsRandomColorRamp QgsRandomColorRamp -> QgsLimitedRandomColorRamp QgsVectorColorBrewerColorRamp -> QgsColorBrewerColorRamp These color ramps are used throughout all of QGIS (not just in vector symbology) and the current names are misleading.
