Circuit Color

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.
