Colors

Use this page when you want to color one mark, line, area, label, or other plot element.

A color token is one named color string, such as "dc.blue6". A family step is one swatch in a related ramp: dc.blue6 is step 6 of the blue family. For separate series or categories, use Palettes.

ax.plot(x, y, color="dc.blue6")

How to read the labels

  • A dartwork family step joins the dc prefix, a family name, and a number, such as dc.blue6.

  • The general format is library.colorweight (for example, tw.blue500, md.red700, or oc.gray6).

  • Works anywhere matplotlib accepts a color—no extra API layer required.

  • dm.style.use("scientific") loads the dartwork style so these names look consistent across lines, fills, markers, and legends.

Every named color token in dartwork-mpl is rendered in the full-width sheets below. The dc.* (“dartwork color”) family is the recommended starting point for publication figures; six third-party design systems are bundled for cross-team consistency.

import dartwork_mpl as dm
import matplotlib.pyplot as plt
import numpy as np

dm.style.use("scientific")
t = np.linspace(0, 2 * np.pi, 200)
plt.plot(t, np.sin(t), color="oc.indigo6", linewidth=2.4, label="Indigo 6")
plt.scatter(t[::12], np.cos(t[::12]), color="tw.rose500", edgecolor="none")
plt.legend()
plt.show()

Palette sheets

dartwork Color — families

The 20 single-hue families — 19 chromatic ramps plus gray — are the perceptual backbone of the system. Each contains ten family steps (dc.blue0 … dc.blue9). Reach any step as a plain string — color="dc.blue6" — anywhere matplotlib accepts a color.

Tip

In plain English Adjacent numbers are designed to progress more consistently, and ordered ramps also keep their accepted light-to-dark ordering under the catalog’s nominal sRGB model. These are design targets, not a promise that every observer sees perfectly equal steps.

See Design rationale for the exact construction and output metrics, and Validation for the model-specific release checks.

Semantic aliases

Role aliases keep meaning separate from hue choice. Use dc.pos and dc.neg for signed data such as gains versus losses, anomalies above or below a baseline, or pass / fail states; use dc.ref for reference lines; and use dc.hl for the one series you want the eye to find first. The pos / neg hues follow the active style’s locale convention (*-kr styles swap to the red-up / blue-down convention).

ax.plot(gains, color="dc.pos")
ax.axhline(baseline, color="dc.ref")

OpenColor. Balanced neutrals and calm hues for dashboards and UI frames. Even weight steps make layered backgrounds straightforward.

Rendering guidance

  • Use weights 400–600 for lines and markers; 50–200 for fills and backgrounds.

  • Pair adjacent weights for related elements (e.g., line at 600, fill at 200).

  • Keep a single library per figure unless you need deliberate contrast (Primer background with Tailwind accents, for example).

  • Turn off edgecolor on dense scatters to keep swatches clean in exports.
