Claim 16:
17. A non-transitory computer-readable storage medium storing instructions that cause a processor to:
determine, for a conversion between a current video block of a video and a bitstream of the video, that a prediction mode is applied to the current video block, wherein in the prediction mode, reconstructed samples are represented by a set of representative color values, and the set of representative color values comprises at least one of 1) palette predictors, 2) escaped samples, or 3) palette information included in the bitstream; and
perform the conversion at least based on the prediction mode,
wherein a first syntax element specifying a quantized value of the escaped sample is included in the bitstream, and wherein a binarization of the first syntax element uses an exponential-Golomb (EG) code of order K, K a non-negative integer that is unequal to three, and
wherein the escaped sample is reconstructed based on a level scale chosen from a list of level scales using an index, wherein the list of level scales is {40, 45, 51, 57, 64, 72}, and the index is determined based on qP % 6, wherein % is a mod sign and qP specifies a quantization parameter.
