Spectrum by ipsfocus
Spectrum is a color-changing theme. It mimics the color of the sky based on the time of day: during the day, the theme is a strong blue and fades slowly into dark colors as the sun sets. During night hours, the theme will be dark which makes reading pleasant. Spectrum also comes with a background picker, allowing your members to choose from a predefined selection of images which faintly overlay your background gradient.

The background of Spectrum adjusts based on the time of day. During day hours, the theme will be a vibrant blue color.
Morning & Afternoon

During night hours, the theme darkens to make reading easy and pleasant.
