London design studio Raw Edges has designed a series of carpets that appear to change colour throughout the day.

The Lake Collection was created for Persian rug company Golran and is based on the optical-art technique ‘lenticular’, commonly used by artists such as Yaacov Agam and Victor Vasarely.

By varying the pile heights in the rugs, Raw Edges have created a patterned carpet that can be perceived differently depending on the viewer's vantage point.

The illusion means that the rugs may look bright and colourful in the morning but become more muted throughout the day, changing their appearance in a way similar to the reflection of water from a lake.

The complete pattern can only be seen at certain times of day from one specific position.

Made in Nepal from hand-knotted silk and wool, The Lake Collection is available in four colours: grey, red, blue and green.
