About Bittersweet
Bittersweet (#FE6F5E) is a light, vivid red. Red sits at the warmest, longest-wavelength end of the visible spectrum and is the most eye-catching hue of all, so this shade balances warmth with a strong sense of energy and presence.
Psychology
Red raises heart rate and energy levels and is strongly linked to passion, excitement and urgency. It grabs attention faster than any other hue, which is why it powers sale signs, alerts and appetite-driven food branding.
Applications

History
Red ochre was among the first pigments used in prehistoric cave art more than 40,000 years ago. Later vivid reds came from cinnabar, kermes insects and madder root, and the modern era replaced them with stable synthetic pigments such as cadmium and quinacridone reds.
