Set the color for rendering the time series line. This allows you to specify exact colors for individual series, overriding the default color palette. Colors can be specified using hex codes, named colors, or ARGB values that include transparency.

Parameters

  • expr: The time series expression to apply color styling to
  • color: Color specification (see supported formats below)

Supported Color Formats

  • 3-digit hex triplet: e.g. f00 is red
  • 6-digit hex RGB: e.g. ff0000 is red
  • 8-digit hex ARGB: e.g. ffff0000 is red with full opacity (first byte is alpha)
  • Named colors: Theme-aware color names that adapt to light/dark themes:
    • blue1, blue2, blue3
    • gray1, gray2, gray3
    • green1, green2, green3
    • orange1, orange2, orange3
    • purple1, purple2, purple3

Alpha Channel Behavior

When using 8-digit ARGB format, the color includes its own alpha channel. If :alpha is applied after :color, it will modify the alpha channel of the previously set color. However, if :color is applied after :alpha, it will override the alpha setting.

  • :alpha - Set transparency (interacts with ARGB colors)
  • :palette - Use color palettes for multiple series
  • :lw - Set line width
  • :line - Set line style
