# Resistor/Capacitor Color Code System

codename: tictac

;F

1. Color Key

Logic: Similar to standard resistor bands (1-8), but Black is stolen for the Decimal Point, White becomes 0, and Indigo is 9.

Color	Value	Hex	Swatch
White	0	#FFFFFF	⚪
Black	.	#000000	⚫
Brown	1	#996633	🟤
Red	2	#FF0000	🔴
Orange	3	#FF9900	🟠
Yellow	4	#FFFF00	🟡
Green	5	#00FF00	🟢
Blue	6	#0000FF	🔵
Violet	7	#FF00FF	🟣
Grey	8	#CCCCCC	🔘
Indigo	9	#4B0082	😈

2. Reading Order

Rule: Start in either corner marked "Start", then sequence the values in a clockwise motion until you have 3 numbers and a decimal.

Start	4	1
2	3	2
1	4	Start

3. Examples

Example A: 100nF (100.)

Reading Sequence: Brown (1) → White (0) → White (0) → Black (.)

❌	⚫	🟤
⚪	⚪	⚪
🟤	⚫	❌

Example B: 0.10uF (0.10)

Reading Sequence: White (0) → Black (.) → Brown (1) → White (0) (Note: This example is rotated 90°)

⚪	⚫	❌
⚪	🟤	⚪
❌	⚫	⚪

4. Guide & Syntax Notes

• Corner Markers: The two "Start" corners will always be transparent (or marked with X in diagrams). If you are uncertain, check the contrast against the background.
• Syntax vs. Math: This encoding is purely syntactical.
  • 100nF looks different than 0.1uF.
  • This is intentional to preserve original formatting.
• Toddler Proof: You don't need to memorize the values to distinguish components; you only need to match the colors.
• The Deviations:
  • Standard resistor bands are used for 1-8.
  • Black is the Decimal Point (instead of 0).
  • White is 0 (instead of 9).
  • Indigo is 9.
