The full-scale schlieren technique was famous and especially developed for flow visualization with large area of test section. This article further presents the color full-scale schlieren technique which captures more colorful images and also promotes the resolution of images. In this work, the developed color full-scale schlieren technique used the light source which penetrates through the linear grating color mask with alternated red, green, and blue colors. The applied light source is made of flat plate and with modular structure which is convenient for varying area of the light source. The width of the grating color lines is 6 mm. The applied area of light source and its test section are 2×2 and 1×1 m2 respectively. In future, this developed color full-scale schlieren technique will be further used for e.g. CO flow visualization during incomplete combustion process of fuel gas. The results in this work show beautiful images and also with expected high sensitivity.
