According to the Flag code of India, the Indian flag has a ratio of two by three (where the length of the flag is 1.5 times that of the width). All three stripes of the flag (India saffron, white and India green) should be equal in width and length. The size of the Ashoka Chakra was not specified in the Flag code, but the Ashoka Chakra must have twenty-four spokes that are evenly spaced. In section 4.3.1 of "IS1: Manufacturing standards for the Indian Flag", there is a chart that details the size of the Ashoka Chakra on the nine specific sizes of the national flag. In both the Flag code and IS1, they call for the Ashoka Chakra to be printed or painted on both sides of the flag in navy blue color. Below is the list of specified shades for all colors used on the national flag, with the exception of navy blue, from "IS1: Manufacturing standards for the Indian Flag" as defined in the 1931 CIE Color Specifications. The navy blue colour can be found in the standard IS:1803-1973.
| Colour | X | Y | Z | Brightness |
|---|---|---|---|---|
| White | 0.313 | 0.319 | 0.368 | 72.6 |
| India saffron (Kesari) | 0.538 | 0.360 | 0.102 | 21.5 |
| India green | 0.288 | 0.395 | 0.317 | 8.9 |

Famous quotes containing the words design, construction and/or details:
“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”
—Freeman Dyson (b. 1923)
“When the leaders choose to make themselves bidders at an auction of popularity, their talents, in the construction of the state, will be of no service. They will become flatterers instead of legislators; the instruments, not the guides, of the people.”
—Edmund Burke (1729–1797)
“Anyone can see that to write Uncle Tom’s Cabin on the knee in the kitchen, with constant calls to cooking and other details of housework to punctuate the paragraphs, was a more difficult achievement than to write it at leisure in a quiet room.”
—Anna Garlin Spencer (1851–1931)
