英文摘要：

The design of color schemes in the urban environment is largely based on the traditional subtractive color system with a relative narrow color range, restricted media, and limited theories and methods, and it is insufficient to cope with the design problems in contemporary cities. This article introduces a new multimedia digital color theory, and develops an alternative design method based on it. The new method integrates traditional pigmented media with digital media;it is capable of producing a richer visual effect, and is more effective in conveying emotional and cultural meaning. By concentrating on the cross section and vertical section of the HSV color hexagonal-pyramid, the design process and the effect of“digital city” are seamlessly connected, and the charm of digital color expression is fully exhibited.
