Command color values should only use Hex values!

Personally, I've found it very confusing to use both hexadecimals and decimals to represent color values when using commands. I had never seen decimals be used for color values prior to this, and I believe hex is far more universal and easily understood. I do understand, that, unlike the hex values that are used (that being the 6 digit ones like #FFFFFF), which do not account for opacity, decimal color values do. However, would it not be simpler for players to use hex, such as #FFFFFFFF (RGBA)? This would be far less confusing, considering players have to go out of their way to convert hex values into their decimal counterparts manually.

Here is an example command using the current (1.20.4) syntax:

/summon text_display ~ ~ ~ {text:'{"text":"test","color":"#FF5521"}',background:1689517}

And the command with the syntax I've suggested:

/summon text_display ~ ~ ~ {text:'{"text":"test","color":"#FF5521"}',background:"#19C7ADB1"}
