Charles X was 66 when he became King. He was far less inclined to continue his brother’s concessions to a constitutional monarchy. He wanted a return to absolute monarchy where the King ruled by divine right.
Charles X did not want to use the bed his brother had been displayed in lying in state after death. Charles sent the bed back to the royal garde-robe and had another made the same size so he could re-use all the very expensive silk decoration. The return to royal blue, lavishly decorated with symbols of the French monarchy including the fleur-de-lys suited his outlook.
