What is the method to avoid mixing shades when using transparency?

One method to avoid mixing shades when using transparency is to use layers with different blending modes. By separating the colors into different layers and adjusting each layer's blending mode, you can create the appearance of transparency without mixing the colors. Additionally, using layer masks to selectively control the areas where different colors overlap can also help prevent mixing. It is also important to use colors that are compatible and blend well together to ensure the desired effect is achieved.
