| Abstract [eng] |
Several factors determine visibility of a presentation in an enlightened room. One of them is colour luminance contrast. Colour lumi-nance contrast reliance on ambient light was explored. On the base of results, foreground and background colour combinations of the best screen-image visibility were determined. The highest colour luminance contrasts can be got in the case of dark background and the foreground of White, Yellow, Cyan or Green colour. Ambient light has the least influence on these colours. The highest colour lumi-nance contrast on White background is with Black and Blue foregrounds only; in the case of Green, Cyan and Yellow foreground colour luminance contrast is low, so these colours should be used only for large objects. Colour luminance contrast of Red and Magenta is low of both negative and positive images; therefore these colours are well-chosen for sizeable objects. |
