💡 About Number Systems
Decimal (Base 10) is the number system we use in everyday life (digits 0-9). Binary (Base 2) uses only 0 and 1 — it is the fundamental language of all computers and digital electronics. Octal (Base 8) uses digits 0-7 and is commonly used in Unix/Linux file permissions. Hexadecimal (Base 16) uses digits 0-9 and letters A-F — widely used in programming, color codes (HTML/CSS), and memory addresses.

💡 About Color Formats
HEX is the most widely used color format in web design — a 6-character code like #FF5733 representing Red, Green, Blue values in hexadecimal. RGB (Red, Green, Blue) specifies each color channel from 0 to 255. HSL (Hue, Saturation, Lightness) is more intuitive for designers — hue is 0-360°, saturation and lightness are percentages. RGBA adds an alpha (transparency) channel from 0 (fully transparent) to 1 (fully opaque).
