Somehow I changed the color hex code to else, need help

[Anderson5CA8]

I don't know how to properly name it, but the color picker was way more simple and easier, specially because I would pick a color I liked and put the hex code in a notepad. But these days it suddenly changed and I don't know how to switch back. Picture is the actual color picker that I don't know how I changed to it and I can't use the hex codes I saved

Turn off the "use system color picker" option in the preferences.
