Button tooltip background and text color matches, does not change if using QToolTip { color: #ffffff; background-color: #000000}

[Cristality_]

I was using custom colors in styleSheet and it also change the tooltip text color to white on white background, making it invisible to see. I tried ToolTip { color: #ffffff; background-color: #000000}in the same styleSheet, but nothing changed. Left some screenshots, maybe they will help.
Any suggestions will be apricated.
