How six characters become a color
In a web style sheet, a color such as `#BADA55` is usually read as three two-character numbers: red, green, and blue. The `#` marks the value as hexadecimal, a base-16 number system that uses the digits 0–9 and letters A–F. Each pair sets the intensity of one color channel, from 00 (none) to FF (maximum).
In this code, `BA` sets red to 186, `DA` sets green to 218, and `55` sets blue to 85 on a 0–255 scale. Green is strongest, with a substantial red component and less blue, so the combination appears as a bright yellow-green.
The joke survives because the browser ignores it
A browser does not read `BADA55` as a word. It parses the characters in pairs and turns those values into light on the screen. The hidden message is for the person reading the code: a memorable bit of wordplay embedded in a perfectly ordinary color value.
That works because hexadecimal gives designers letters as well as digits, while remaining compact enough to fit into a single CSS declaration. The result is both functional and easy to recognize later—a color setting that looks like a boast, even though the browser sees only three channel values.
