PCT No. PCT/SE97/01020 Sec. 371 Date Feb. 8, 1999 Sec. 102(e) Date Feb. 8, 1999 PCT Filed Jun. 11, 1997 PCT Pub. No. WO98/00670 PCT Pub. Date Jan. 8, 1998The present invention relates to a multi-color gobo for the projection of a multi-color pattern, and to a method of manufacturing the gobo. On the basis of a multi-color pattern that is color-separated into single-color components, the single-color components are disposed to parallel planes in the gobo and at least two of these planes are mutually separated by means of a transparent substrate. The gobo may include a plurality of mutually superimposed disc-shaped and transparent substrates and each of the substrates may include a dichroic surface coating so as to form a color filter. Combinations of the color filters are able to reproduce the colors of the multi-color pattern and respective color-emitting surface coatings present a pattern that coincides with the pattern of corresponding color components in the multi-color pattern.
