How Color Hex Codes Work: A Beginner Guide
#FF5733 looks like random characters until you understand the 6-digit pattern.
A hex color code is a 6-character representation of a color using the RGB system. Characters 1-2 = red (00-FF). Characters 3-4 = green (00-FF). Characters 5-6 = blue (00-FF). #FF0000 is pure red (maximum red, no green, no blue). #FFFFFF is white (all channels at max). #000000 is black (no color at all).
Quick Reading Guide
First two characters high (FF, CC, etc) = reddish. Middle two high = greenish. Last two high = bluish. Equal values across all three = shades of grey. #808080 is medium grey. #C0C0C0 is silver. Understanding this pattern lets you read any hex code and roughly know the color without seeing it rendered.
