Color simulation method using image processing software
Two points to consider for color simulation using color processing software were examined in this study. They are how to reserve texture of surface in the image and how to change shadow part of the area of color alternation correctly as same as the bright part. For the first point, the technique which changes the luminance separately from the hue and saturation of the color can remain the information of the distribution of luminance. The author found the luminance value calculated by the formula L=0.3<*>R+ 0.6<*>G+0.1<*>B should change color correctly. For the second point, the mere color matching of the bright area couldnt change the shadow part correctly. According to the measurement of the gradation of several cubes covered by varying achromatic colors in a sample image, the modification method of the tone curve dialog in Adobe Photoshop is proposed. The tone curve should be a straight line and the gradient seems to vary according to the luminance distribution of the setting and the surface condition.
