Hi, just one way how you can create a random color via xpath on a button press. is to create a random number from 0 to 0xffffff, then add leading 0 until you reach 6 digits, prefix the whole thing with # Code:
'#'|| pad-string-left(
integer-to-hex-string( xs:integer ( fn:random-number-generator(fn:current-dateTime())?number * hex-string-to-integer('ffffff') ) ),
6, '0' )

Hi,
Thanks for the hint how to get a random color through its recording in RGB, but I don’t understand how to set the background color by clicking. This is where help is needed :)

just create an attribute, element, variable,... for your bk color.
Initialize with whatever color you want "#000000" for black for example.
Assign this element to the tables background color.
On button click:
update node -> your bk color element,...
with result of -> the random color code
