Circuit Color is a lightweight electronics reference app that helps you decode resistor color bands in seconds. Designed for students, makers, and technicians, it delivers fast, accurate values without digging through charts.
Core features include an interactive resistor color code calculator for 3–6 band resistors, SMD resistor code lookup, and quick Ohm’s Law calculations for voltage, current, resistance, and power. Clear readouts with tolerance and temperature coefficient make it ideal for bench work and classroom use.
Fast, offline, and easy to use, Circuit Color streamlines your workflow with an intuitive color picker, unit conversions, and dark mode. Keywords: resistor color code calculator, electronics reference app, Ohm’s Law calculator, circuit tools, utilities.

How to use:
1. Download and open the app, then choose a tool such as Color Bands, SMD Codes, or Ohm’s Law.
2. For Color Bands, tap each band and select its color to instantly see resistance, tolerance, and temperature coefficient.
3. Switch between 3–6 band modes, change units, and view E-series values for quick part selection.
4. Use the SMD tool to enter numeric or alphanumeric codes and get the corresponding resistance value.
5. Open Ohm’s Law, input any two known values, and the app calculates the rest; save or share results as needed.
