color link

The color namespace provides functions to work with colors and access their components. Colors are used throughout PyneCore for visual elements like lines, labels, plots, and overlays. You can create colors from RGB values, modify transparency, interpolate between colors using gradients, and extract individual color components.

Quick Example link

  from pynecore.lib import close, high, low, color, Color, ta, script

@script.indicator(title="Color Demo", overlay=True)
def main():
    # Use predefined colors
    plot_color: Color = color.green if close > ta.sma(close, 20) else color.red
    
    # Create custom color with transparency
    transparent_blue: Color = color.new(color.blue, transp=50)
    
    # Create color from RGB values
    custom_color: Color = color.rgb(255, 165, 0)
    
    # Create color gradient based on price position
    price_position: float = (close - low) / (high - low) if high != low else 0.5
    bar_color: Color = color.from_gradient(
        price_position, 0, 1, color.red, color.green
    )
    
    # Extract color components
    red_val: int = color.r(plot_color)
    green_val: int = color.g(plot_color)
    transp_val: int = color.t(plot_color)
  

Functions link

r() link

Retrieves the red component of a color.

Returns: int — The red component value (0-255)

  red_comp: int = color.r(color.blue)  # 41
  

g() link

Retrieves the green component of a color.

Returns: int — The green component value (0-255)

  green_comp: int = color.g(color.lime)  # 230
  

b() link

Retrieves the blue component of a color.

Returns: int — The blue component value (0-255)

  blue_comp: int = color.b(color.aqua)  # 212
  

t() link

Retrieves the transparency component of a color.

Returns: int — The transparency value (0-100, where 0 is fully opaque and 100 is fully transparent)

  transp: int = color.t(color.new(color.red, transp=75))  # 75
  

new() link

Creates a new color with modified transparency, optionally accepting a color object or hex string.

Returns: Color — Color with the specified transparency

  semi_transparent: Color = color.new(color.blue, transp=50)
custom_hex: Color = color.new("#FF5733", transp=25)
  

rgb() link

Creates a new color from RGB component values with optional transparency.

Returns: Color — Color with the specified RGB values and transparency

  orange: Color = color.rgb(255, 165, 0)
translucent_purple: Color = color.rgb(156, 39, 176, transp=50)
  

from_gradient() link

Interpolates a color from a gradient based on a value’s position within a range. Values outside the range are clamped to the corresponding endpoint colors.

Returns: Color — Interpolated color based on value’s position in the range

  bar_color: Color = color.from_gradient(close, low, high, color.red, color.green)
  

Constants link

Compatibility link

All color functions and constants are fully supported in PyneCore. The namespace provides complete compatibility with Pine Script v6 color operations.
