Curated palette · Scales
Seven palettes for data with an order, and two well-known ones to avoid. Each is measured here with this site's color engine: whether its lightness climbs evenly, whether it keeps its order in grayscale, and whether its steps and its two sides can still be told apart with color vision deficiency.
The nine palettes, low to high. Select one to read why.
Live heatmap
Hours of daylight by latitude and month, in nine classes. Choose a palette and a type of color vision; every cell keeps its number, so color is never the only cue.
The controls need JavaScript. Without it the map shows viridis, as typical vision sees it.

Day length works with both kinds of palette. Read as a quantity, from short days to long ones, it is sequential. Read against 12 hours, when day and night are equal, it is diverging: the middle class holds the equator all year, and every latitude in March and September.
The hours are computed, not measured: sunrise to sunset at the center of the sun, with Cooper's 1969 formula for the sun's declination and no atmospheric refraction, so real days run a few minutes longer. The classes are 1.5 hours wide and centered on 12 hours, so every palette colors the same cells the same class.
Measured
Lightness says whether a palette shows order; CIEDE2000 under simulation says whether its steps, and its two sides, can still be told apart. The verdict follows from the checks: a sequential palette must rise in lightness and keep that order in grayscale, a diverging one must keep its sides at least noticeably apart under every color vision.
| Palette | Lightness, low to high | Even steps | In grayscale | Closest neighbors | Verdict |
|---|---|---|---|---|---|
| viridis | 0.285 → 0.918 Rises at every step | 0.82 | Order kept | 4.55 Protanopia, stops 8 and 9 | Use it |
| cividis | 0.259 → 0.921 Rises at every step | 0.84 | Order kept | 6.83 Tritanopia, stops 8 and 9 | Use it |
| Blues | 0.986 → 0.322 Rises at every step | 0.44 | Order kept | 3.53 Achromatopsia, stops 1 and 2 | Use it |
| YlGnBu | 0.990 → 0.260 Rises at every step | 0.27 | Order kept | 2.44 Achromatopsia, stops 1 and 2 | Use it |
| jet | 0.271 → 0.377 Turns back after stop 6 | 0.00 | Order lost | 0.22 Achromatopsia, stops 4 and 5 | Avoid |
| Palette | Lightness, end · middle · end | Balance | Two sides apart | Closest neighbors | Verdict |
|---|---|---|---|---|---|
| RdBu | 0.492 · 0.976 · 0.505 Lightest in the middle | 0.013 | 16.47 Protanopia, stops 4 and 6 | 4.45 Achromatopsia, stops 5 and 6 | Use it |
| PuOr | 0.562 · 0.976 · 0.389 Lightest in the middle | 0.172 | 20.12 Tritanopia, stops 4 and 6 | 4.01 Achromatopsia, stops 4 and 5 | Use it |
| BrBG | 0.493 · 0.970 · 0.459 Lightest in the middle | 0.034 | 13.17 Protanopia, stops 4 and 6 | 2.52 Achromatopsia, stops 4 and 5 | Use it |
| RdYlGn | 0.575 · 0.985 · 0.598 Lightest in the middle | 0.030 | 0.52 Deuteranopia, stops 4 and 6 | 4.60 Achromatopsia, stops 5 and 6 | Avoid |
Color vision
Each palette under typical vision, the three dichromacies at full severity, and in grayscale. A sequential palette should still run from one end to the other; a diverging one should still show two sides.
The simulation is the model of Machado, Oliveira and Fernandes (2009) at full severity, the one this site's simulator uses; achromatopsia is shown as luminance only, which is also how the palette prints in black and white. A simulation approximates how colors collapse; it does not reproduce anyone's vision.
Use it well
First decide what kind of data you have; then pick from that kind. Every reason below is a measurement from this page.
Use it for The default for a quantity on screen: heat maps, density, any value from low to high. Lightness climbs in near-even steps (0.82), so equal differences in the data look about equal, and it keeps its order in grayscale.
Watch for Its stops 8 and 9, green-yellow to yellow, come within ΔE 4.55 under protanopia. Label the top of the legend.
Use it for When readers with color vision deficiency are a main audience: it was designed for them. Every neighboring step stays at ΔE 6.83 or more under all five simulations, the only palette here that does.
Watch for It runs from blue to yellow only, so it is quieter than viridis. Its lightness steps are the most even here (0.84).
Use it for A map of one quantity in a few classes: rates, shares, density by region. A single hue keeps the message simple: darker means more.
Watch for Its lightest stop is 1.03:1 against white, so a white page swallows it: outline every region. In grayscale its stops 1 and 2 come within ΔE 3.53.
Use it for More classes than one hue can separate: hue changes with lightness, so neighboring classes are at least ΔE 8.19 apart in typical vision, against 5.09 for Blues.
Watch for Its pale end bunches: stops 1 and 2 are ΔE 2.44 apart in grayscale and 3.18 under tritanopia. Label the low end of the legend.
Why to avoid it Lightness rises to stop 6 and falls again, so the brightest band, cyan to yellow, looks like a feature of the data wherever it lands. In grayscale, stops 4 and 5 are the same gray (ΔE 0.22) and the order is lost.
Use instead viridis, which spans the same range of lightness without turning back.
Use it for Data with a meaningful middle: change from a baseline, anomalies, correlation from −1 to 1. Its two sides are balanced in lightness (within 0.013) and stay at least ΔE 16.47 apart under every color vision.
Watch for In grayscale the two sides meet, never more than ΔE 3.65 apart: print the values, or a legend with signs.
Use it for A diverging palette with no red and no green, and none of red's sense of alarm. Its two sides stay at least ΔE 20.12 apart under every color vision.
Watch for Its purple side is darker than its orange side, by 0.172 in lightness at the ends, so high values look weightier than low ones. If both directions matter equally, use RdBu.
Use it for Two directions with an earthy feel: wetter or drier, vegetation gained or lost. Balanced within 0.034.
Watch for Under protanopia, stops 5 and 6 come within ΔE 3.23. Label the classes nearest the middle.
Why to avoid it Under deuteranopia, the most common color vision deficiency, its two sides meet: the stops beside the middle are ΔE 0.52 apart, and even its two ends only 9.57. A reader cannot tell above the middle from below it.
Use instead RdBu or PuOr, whose sides stay apart under every color vision.
In code
All seven ship with matplotlib and with d3. The calls below give exactly the nine stops measured here; for the three diverging palettes in matplotlib, pass the stops yourself.
| Palette | matplotlib | d3 | Note |
|---|---|---|---|
| viridis | colormaps["viridis"].resampled(9) | d3.quantize(d3.interpolateViridis, 9) | Both give exactly these nine. |
| cividis | colormaps["cividis"].resampled(9) | d3.quantize(d3.interpolateCividis, 9) | d3's cividis is a polynomial fit, up to 13 of 255 away in one channel; matplotlib's is exact. |
| Blues | colormaps["Blues"].resampled(9) | d3.schemeBlues[9] | Both give exactly these nine. |
| YlGnBu | colormaps["YlGnBu"].resampled(9) | d3.schemeYlGnBu[9] | Both give exactly these nine. |
| RdBu | ListedColormap(stops) | d3.schemeRdBu[9] | matplotlib's own RdBu runs through ColorBrewer's 11 classes: these nine and a darker stop at each end. |
| PuOr | ListedColormap(stops) | d3.schemePuOr[9].slice().reverse() | d3 lists PuOr from the purple end, so reverse it to match ColorBrewer and this page. |
| BrBG | ListedColormap(stops) | d3.schemeBrBG[9] | matplotlib's own BrBG runs through the 11 classes, as RdBu does. |
In matplotlib, colormaps and ListedColormap come from matplotlib and matplotlib.colors; stops is the palette's list from the JSON export below. Every name was run against matplotlib 3.10.8 and d3-scale-chromatic 3.1.0 before publishing.

Where the palettes, the data and the measurements come from.
viridis, cividis and jet are matplotlib's 256-color tables at entries 0, 32, 64 … 224 and 255; the ColorBrewer schemes are their 9-class versions, the same in the colorbrewer package and in d3. Lightness is OKLCH L; differences are CIEDE2000; simulations apply Machado's matrices in linear light at full severity. Node tests recompute every number on this page from the site's color engine. Checked with axe and the keyboard in Chromium; not yet tested with a screen reader. Last reviewed on 14 October 2026.
This product includes color specifications and designs developed by Cynthia Brewer (http://colorbrewer.org/).
