1. A video processing method, comprising:
receiving a first palette entry for palette coding a target coding unit (CU);
determining whether the target CU is part of a single-tree slice;
determining whether the target CU is coded with separate luma and chroma trees; and
in response to the target CU being determined to be part of a single-tree slice and to be coded with separate luma and chroma trees,
encoding a first component of the target CU based on the first palette entry, and
encoding a second component of the target CU based on a default palette entry.
