Overview

Colors in the Darvas indicator API are expressed as 8-character hex strings in #RRGGBBAA format, where the last two characters are the alpha channel (FF = fully opaque, 00 = fully transparent). The color namespace provides named constants and construction helpers.

​
Constructing colors

​
color.new(hexString, transparency?)
string
Create a color from a hex string with optional transparency (0-100, where 100 = fully transparent).
color.new("#FF0000", 0)   // fully opaque red: "#FF0000FF"
color.new("#FF0000", 50)  // 50% transparent red: "#FF000080"
color.new("#FF0000", 100) // invisible: "#FF000000"
For the full list of color.* functions including color.rgb, color.from_gradient, color.r, color.g, color.b, and color.t, see the custom indicator spec.

​

Dynamic coloring example

const bullColor = input.color("Bull", "#22c55eFF");
const bearColor = input.color("Bear", "#ef4444FF");

plot("Candle color", null);

onBar(() => {
  const isBull = ctx.close() >= ctx.open();
  barcolor(isBull ? bullColor : bearColor);
  plot("Candle color", ctx.close());
});

​
Transparency with color.new

// RSI overbought zone shading
const obColor = color.new("#ef4444", 80); // very faint red fill

onBar(() => {
  const rsi = ta.rsi(ctx.close, 14);
  bgcolor(rsi > 70 ? obColor : null);
});

Plot basics

color option for plot series.

hline, fill, bgcolor

bgcolor and barcolor use the same color format.

Line entity

Entity colors also use #RRGGBBAA format.
