Goethe assigned numbers to primary and secondary hues based on their luminosity (ability to give a glowing impression). White, as the most luminous, is given the number 10, followed by yellow (9), orange (8), red (6), green (6), blue (4), violet(3); while black, as the least luminous is 0. The numbers are used to match these colours, creating pairs of complementary colours. Each pair consist of a light hue and a dark hue : yellow – violet, orange-blue, and red-green.

This knowledge therefore can be further used in the space because our eyes in reality require any given colour along with its complementary. This is due to the way complementary colours provide psychological balance in satisfying the needs of both warm and cool colours.

People have a strong tendency to unconsciously seek warm and cool hues in the same space. This has been proven by Louis Cheskin, a colour consultant and author. Cheskin did an experiment with three rooms coloured in green. The first one was painted in a single shade of green. The second one is treated in three values of green. While the last one also used three values of green yet he added the colour wine red, which is the complementary of one of the values of green. The occupants of the first room gave a negative reactions due to monotony. Occupants of the second room did not show any defined respond, either favourable or unfavourable. While occupants in the last room showed 94% favourable reactions. ( Danger, Eric P., 1987)

By using complementary colours in the space, a sense of perceived balance in the space can be achieved. The balance achieved is not only pleasing for the eyes but also contribute to changing the mood of the user to support both active and passive activities.

Example of the contrast between bright and dark spaces can be seen from the work of Philippe Starck in Le Lan Restaurant in Beijing. The colours used varied between warm and cool colours. Light is used to illuminate seating areas, leaving the spaces in between the clusters of seats appear darker. Instead of using solid walls, colourful curtains are used to define boundary of the space. The contrast is achieved not only through combining both light and dark in the same space, but also through the colour contrast between the furnitures placed in the space.

Even in private house, application of bright and dark spaces can add excitement to our daily life. This is evident in the work of Luis Barragan in a house of Fransisco Gilardi.
