Using Colors in Your Scripts

​
Single Color Plot

Use a single color constant for simple line plots: 
//@version=2

define("Simple SMA", "onchart", true);

timeseries trade = ohlcv(currentSymbol, currentExchange);
var sma20 = sma(trade, 20, 4);

// Use a single color constant
plotLine(value=sma20, width=2, colors=["orange"], label=["SMA 20"], desc=["20-period Simple Moving Average"]);

​
Multi-Color Indicators

Combine multiple colors for complex multi-line indicators: 
//@version=2

define("Multi-MA", "onchart", true);

timeseries ohlcvData = ohlcv(currentSymbol, currentExchange);

var sma10 = sma(source=ohlcvData.close, period=10);
var sma20 = sma(source=ohlcvData.close, period=20);
var sma50 = sma(source=ohlcvData.close, period=50);

// Use multiple color constants
plotLine(value=sma10, width=2, colors=["blue"], label=["SMA 10"], desc=["10-period SMA"]);
plotLine(value=sma20, width=2, colors=["orange"], label=["SMA 20"], desc=["20-period SMA"]);
plotLine(value=sma50, width=2, colors=["green"], label=["SMA 50"], desc=["50-period SMA"]);

​
Conditional Colors

Use color arrays with colorIndex to change colors based on conditions: 
//@version=2

define("RSI Colored", "offchart", true);

timeseries ohlcvData = ohlcv(currentSymbol, currentExchange);
var rsiValue = rsi(source=ohlcvData.close, period=14);

// Color based on RSI level
var colorIndex = rsiValue > 70 ? 0 : (rsiValue < 30 ? 1 : 2);

plotLine(value=rsiValue, width=2, colors=["red", "green", "blue"], colorIndex=colorIndex, label=["RSI"], desc=["RSI with conditional colors"]);
Pre-designed color combinations that work well together for different types of indicators.

​
Trading Signals

Classic colors for buy/sell signals and trend indicators: 
var colors = ["green", "red", "blue"];

​
Technical Analysis

Professional colors for technical indicators and overlays: 
var colors = ["orange", "purple", "teal"];

​
Volume Analysis

Distinct colors for volume-based indicators: 
var colors = ["lime", "yellow", "fuchsia"];

​
Best Practices

​
Consistent Branding

Use the same color scheme across related indicators for visual consistency.

​
Accessibility

Choose colors with sufficient contrast for better readability. Avoid relying solely on color to convey information.

​
Semantic Colors

Use meaningful colors that match user expectations:
  • Green for bullish signals, gains, positive values
  • Red for bearish signals, losses, negative values
  • Blue for neutral indicators and reference lines
  • Orange/Yellow for warnings and attention-grabbing elements
