Demonstration of the bluish color on veins
Abstract:
This study aimed to demonstrate and quantify the greenish-blue color of veins using tissue paper and stocking via the simultaneous color contrast phenomenon. The colors of real skin and veins were accurately measured in the experiment and used as a reference to simulate the color of the skin and the veins. Subcutaneous veins were simulated using gray paper covered with tissue paper for Experiment 1 and stockings for Experiment 2. The color appearance was quantitatively measured by the elementary color naming method. The results suggest that tissue paper and stockings were used to enhance a stronger simultaneous color contrast of the veins. Moreover, the color of the veins appeared complementary to the color of the skin.
