1. An image decoding method, comprising:
receiving a video stream;
obtaining color remapping information for remapping of reconstructed samples of an image from the video stream,
wherein the color remapping information includes coefficients information representing three-by-three color remapping matrix coefficients,
decoding the image from the video stream,
wherein the color remapping information further includes color primaries information for defining a color space for a remapped image,
wherein the color primaries information indicates red (R), green (G) and blue (B) primaries of the color space of the remapped image,
wherein the color remapping information further includes a first mapping information for converting values of color components in a color space of the decoded image into values of color components in a reference color space,
wherein the color remapping information further includes a second mapping information for converting the values of the color components in the reference color space into values of color components in the color space of the remapped image,
wherein the video stream includes a Supplemental Enhancement Information (SEI) message,
wherein the color remapping information is included in the SEI message.
