Why are white glowing words brighter than other colors among the many colors? Black and white luminous words why as long as a larger will some light is not very symmetrical? Do all the different colors of the letters have the same effect? These let shenzhen blue king photoelectric and we discuss together.
We know that the brightness of different luminous words is not the same, color brightness is also known as brightness, brightness: refers to the relative brightness of color, usually from 0% (black) to (white) percentage to measure. In terms of brightness, light is white and dark is black.
Here I use some common colors to compare their RGB
1. Red R255 G0 B0 L (brightness) : 54
2. Blue R000 G0 B255 L (brightness) : 30
3. Yellow R255 G255 B0 L (brightness) : 98
4. White (R255 G255 B255) L (brightness) : 100
From the above comparison, we can see that the brightness of white is 100, the brightness of yellow is 98, the brightness of blue is 30, and the brightness of red is 54. The small conclusion can be drawn that the darker the color is, the lower the brightness will be in general! Red, green and blue are different in proportion to white. The root cause is that the retina of the human eye is sensitive to different wavelengths of light. After a large number of experimental tests, the following approximate proportion was obtained for reference design: the brightness ratio of simple red, green and blue was 3:6:1, and the brightness ratio of red, green and blue was 3.0:5.9:1.1
