Amber (#FFBF00) is a vibrant warm color that perfectly bridges yellow and orange on the color wheel. This rich, golden hue captures sunshine's energy while maintaining the sophistication of fossilized tree resin from which it takes its name.

In design, amber excels as an accent color for creating visual hierarchy and drawing attention to key elements like call-to-action buttons. Its warm undertones make interfaces feel inviting and energetic, promoting feelings of confidence and vitality. The color works beautifully paired with deep browns and forest green for earthy palettes, or alongside navy blue for striking contrast.

Amber's psychological impact is particularly powerful—it stimulates enthusiasm and sparks creativity while maintaining an approachable, friendly atmosphere. However, use it sparingly in large spaces as its intensity can overwhelm. Instead, leverage amber strategically for highlights, interactive elements, or brand accents where you want to convey energy and warmth.

Interestingly, this exact shade appears in traffic lights worldwide, where it signals "prepare to stop"—demonstrating amber's natural ability to command attention and communicate important information effectively.
