Ability to paint on maps and in book and quills

Please add a little painting system that can be activated by a paintbrush icon in the bottom left corner of maps and book and quills to open a menu with a hex and rgb value input boxes for the color along with a table of common colors like red, orange, yellow, green, blue, purple, black, white, and brown, you would also have an eraser tool to erase. The interface wound have a checkmark in the top left corner that would save your image and close the painting interface, their would be an X on the top right that would close the interface without saving the image, The paintbrush icon for coloring would be right of the checkmark with the eraser below the paint brush, when either the paintbrush or eraser is selected the icon would be outlined to show that that tool is in use, to the right of the paintbrush and eraser icon there would be a slider to change the size of the paintbrush or eraser with the size indicated above the slider. The hex input area for the color would be left of the X button with the rgb input area below the hex input, to the left of the hex and rgb input felids would be a vertical rectangle that displays the color that is currently being used. The common colors would be listed in a grid in between the checkmark and X, if one of the listed colors is selected it would be outlined as well. You would paint on a grid that is 128 by 128 pixels for book and quills and maps of every size.
