I Love Hue (available on iOS and Android) is a game that sharpens perception.

I play it to tune up how I see while simply enjoying color.
This practice offers real results when I make art.

“I Love Hue is a gentle journey into colour and perception, lovingly made for players who enjoy beautifully crafted puzzle games – or anyone who needs a few moments of visual tranquility.”

COLOUR – Move each tile to its perfect place within the spectrum
HARMONY – Create order out of chromatic chaos
PERCEPTION – Learn to see the smallest differences between shades
SERENITY – Lose yourself in a tranquil world of colour and light
