Flag of The Republic of China - Construction Details

Construction Details

The specific designs of the flag are located in the "Law about the national flag and emblem of the Republic of China." The ratio of the flag is 2:3, with most of it being red. One-fourth of the flag is blue, which contains the 12 pointed sun. Each sun ray is 30 degrees, so the total sun rays will make up a complete 360 degree circle. Inside the sun, the blue ring is the diameter of the white sun divided by 15.

In later years, more specifics of the canton area (also used as the flag of the KMT), were codified into law. In the drawing released in "Law on the Party and National Flag Manufacturing and Methods" (黨旗國旗之製造及使用辦法), the sun was drawn in more specific detail and mathematical values were given to all elements in the flag. In the law, the canton still had a ratio of 2:3, but the math values given were 24x36 meters. The diameter of the sun with rays is 6/8ths of height of the flag, so in this case, it will be 18. The diameter of the white sun without the sun rays is 1/4 of the width of the canton, so it is 9. The blue ring that is on top of this sun and part of the rays is 1/15 diameter of the white sun, so the size will be 0.6. The angle of the rays, 30 degrees, and the total number of rays have not changed.

The colors of the national flag are dark red, white and dark blue. The KMT party flag just uses white and dark blue and both flags are to be topped with a golden finial. The law doesn't list any specific color processes, such as Pantone, to manufacturing or drawing the flag. Other publications, such as the Album des pavillons nationaux et des marques distinctives, have given approximations for Pantone colors. The dark blue color is Pantone 301c and the dark red is Pantone 186c. Album des pavillons also gave the approximate CMYK colors for the flag; dark blue is 100-45-0-10 and dark red is 0-90-75-5.
