The Magic Color Rectangle from the marketplace does not automatically adjust the size of the rectangle like the normal rectangle component does. I want to use magic color for rectangles on user messages (the rectangle will increase size given how long the message is). Adding the magic text for the normal rectangle component color would help greatly.

Magic text, but then for colors of objects. The option to get a hex code from a text property in your database. If this is possible, you can also add a dark mode to your app by adding one or two text property's to the user where the hex codes of all the objects are stored.

If the user selects dark mode, the user gets updated. The text property changes (for example) to #000000 instead of #FFFFFF. Then all the objects get the updated color because you set the color of the object (like a rectangle) to current user -> hex code (name of text property).
