In traditional architecture ornamentation is in form of carved figures, sculptures of stone as we see it in our traditional Indian Temples. In modern buildings ornamentation is minimum and it is in form of juxtaposition of various materials like stone next to wood, plaster next to glass and so on. Colours and textures have visual weight. Objects with more visual weight attract our attention first and take up most of our attention when in sight. Therefore significant objects, spaces are coloured and textured with more visual weight or are subjected to brighter light as discussed earlier.
Colours render character to space.
A dark floor and a light roof renders a totally different character to space from that rendered by a dark roof and a light floor. Character of space is also affected by psychology of the observer. It is affected by his expectation. The person if walks in a long and narrow corridor and suddenly comes across a single huge hall, to him,the hall seems much larger than it actually is, to because he immediately left very small space. Thus being inside a building should be an experience made by the sequence in which spaces are walked through.
