Creating color difference and improving the color resolution in digital imaging is crucial for better application of color analysis. Herein, a novel color modulation analysis strategy was developed by using a homemade tunable multiband laser illumination device, in which the portions of R, G, and B components of the illumination light are discretionarily adjustable, and hence the sample color could be visually modulated continuously in the RGB color space. Through this strategy, the color appearance of single gold nanorods (AuNRs) under dark-fi...
