Windows.Devices.Lights.LampArray.SetSingleColorForIndices

-description

Sets all lamps specified to the same color.

-parameters

-param desiredColor

The desired color.

-param lampIndexes

Array of lamp indexes to set.

-remarks

If the lamp doesn't support the desired color, it is set to the NearestSupportedColor

If an index does not exist on the device, it is ignored and the remaining are still applied.

Black is equivalent to a lamp being 'off'.
