#FFEF19 Hex Color

Using #ffef19 directly against white creates a lack of visual weight that makes the yellow appear washed out and difficult to read. You should pair this neon yellow with charcoal or deep black instead to maintain high contrast and luminosity.

Because #ffef19 is such an intense neon yellow, it functions most effectively as a sharp accent rather than a primary background color. Use it for call-to-action buttons, highlights, or small graphic elements to draw immediate attention without overwhelming the viewer.
