Work smarter in greyscale
Keep your greyscale forms simple. Some forms aren’t shown through tones – they’re simply indicated through shifts in colour. Hue transitions can trick the eye into seeing forms that aren’t greyscale. Depending on the material, you may need to use several layer styles to achieve the colour and contrast you want. For example, use an Overlay layer to increase contrast, or a Color layer style to preserve existing contrast in the scene.
