Ffff66 works best when it is chosen with contrast, surrounding colors, and interface state in mind. Use the HEX value for static CSS, RGB when you need channel-level control, and HSL when adjusting lightness or saturation for hover states. The CMYK value is an approximate screen-to-print conversion, so print workflows should still rely on calibrated design software or a printer profile.
