After I upgraded my Cesium from 1.2 to 1.3 the colors became much darker than they were previously. The code to create the objects or colors has not been changed, and when I return to 1.2 the colors are back to normal. The colors are set like this:
attributes = b.primitive.getGeometryInstanceAttributes(“B” + b.id);
var color = getHouseColor(b.score);
attributes.color = Cesium.ColorGeometryInstanceAttribute.toValue(Cesium.Color.fromBytes(color.r, color.g, color.b, buildingalpha));
Here are some images to illustrate:
If you have any more questions please ask me. Thanks in advance for any and all advice.
