Inspiring songwriters, painters, and poets, the beautiful shades of twilight are also the inspiration behind Twilight Hypercolor Thinking Putty®. Twilight is the time of day when the sun sets into dusk. As the sun dips below the horizon, its rays refract and scatter against the atmosphere to shine a bright blue one last time. This putty starts out that same deep purple and turns an almost fluorescent blue to mirror the last flash of evening light.
