A vivid, almost fluorescent lemon yellow with a faint greenish tint, this shade feels electric and highly energetic.

It pairs well with deep navy, charcoal, and cool purples for contrast, or with muted grays to temper its intensity. Use it sparingly as an accent, call-to-action, or signage color—too much can overwhelm and reduce legibility against light backgrounds.
