Custom Grayscale Blocks

Grayscale blocks typically refer to color blocks composed of grayscale cards or grayscale graphics of varying brightness. They are used to represent the light and dark levels from black to white, and are commonly used in photography, industrial automation, and other scenarios to help determine the brightness, contrast, layering, and detail of an image.

1. Product Features

(1) Clear Brightness Levels: Composed of black, dark gray, medium gray, light gray to white, it can intuitively represent changes in brightness.

(2) Simple Colors: It basically does not rely on hue and saturation, emphasizing the relationship between brightness.

(3) Obvious Contrast: The contrast between different gray levels can enhance the sense of layering in the image.

(4) Easy to Recognize: The visual information is relatively simple; even without color, different areas can be distinguished by brightness.

(5) Helps Control Image Layering: By adjusting the grayscale, the visual focus, sense of space, and overall brightness and darkness can be controlled.

2. Application Areas

Commonly used in photography, industrial automation, and other scenarios.
