#1a0001 is a hexadecimal color, used commonly to make text or background on a webpage a certain color. It is a very deep red, almost black color. #000000 is the hexadecimal code for black, which would be more commonly used.
Each hexadecimal digit represents four binary digits (bits) (also called a "nibble"), and the primary use of hexadecimal notation is as a human-friendly representation of values in computing and digital electronics. For example, binary coded byte values can range from 0 to 255 (decimal) but may be more conveniently represented as two hexadecimal digits in the range 00 through FF. Hexadecimal is also commonly used to represent computer memory adresses.
The hexadecimal system is base 16.
These are used quite often to represent values stored in bytes - 1 byte is represented as two hexadecimal digits. For example, both the MAC address of a network card and the new IP addresses (IPv6) are usually shown as hexadecimal.

hexadecimal numbers are the a positional numeral system with a radix, or base, of 16.16 distinct symbols are used in the hexadecimal numbers.
In total, there are 2563 possible color values. This is more than 16.7 million, or to be exact, 16,777,216! The 2563 hexadecimal color values range from #000000-#FFFFFF. Our eyes cannot actually detect the difference between all of these colors. Written by: Cheryl Koppel
The attribute that changes a webpage's background color is the CSS property background-color. This property can be applied to the entire page by using the body selector in a stylesheet or inline style. For example, you can set it using body { background-color: blue; } to change the background color to blue. Additionally, it can be set using hexadecimal or RGB values to achieve various colors.
The number 11, (in hexadecimal) is the letter 'b'
A series of 4 bits is called a "nibble." In computing, a nibble can represent 16 different values (from 0 to 15) and is often used in conjunction with bytes, which consist of 8 bits. Nibbles are commonly used in hexadecimal representation, where each nibble corresponds to a single hexadecimal digit.
n isn't used in the hexadecimal system, any more than it's used in decimal (everyday) numbers.
