When should red or color LED signs be used?
For simple informational signs, red is often sufficient. Color adds interest and contrast over a monochrome red-only sign. The green and amber colors are considered softer colors and may be more appropriate for some environments. Color signs can be 3 color, (red, amber, and green), 9 colors, (additional shades of red, amber and green), 256 colors, (mixes of red and green) or 262,000 or 4,000,000 for full color displays.
