UHU 廣告彩混一起是否有法學反應?

UHU color dye , 我不知是何種色彩 , 通常色彩混合不會有化學reaction . If you worry about , you can set up mixing the color dyes in very small portion (a few gms) . Then after the mixing , you can see if there is any changes in temperature , any odor or gases evolved . If nothing happens , just the color change , then there is not any chemical reaction taken place .
