This picture of Pope Francis, happy in his Bird of Paradise traditional headset, was taken during his visit of Vanimo, Papua New Guinea. This small city gave its name to one of these Diverging scientific color palettes (www.researchgate.net/publication/...)

💛💙💜 Cyan Magenta Yellow contrasts in both microscopy images and heatmaps throughout the paper 💛💙💜

uh oh

Here is a thread showcasing my GitHub repositories: 1) Friends Don't Let Friends Make Bad Graphs. An opinionated essay on good and bad graphs. My popular one by a long shot with 6.4k stars and 248 forks. github.com/cxli233/Frie...

Having a color-blind colleague is a good reminder that we need to be more careful when designing figures for scientific publication 🧪 My lab has found this page especially useful for selecting color palettes, used in combination with different symbols: thenode.biologists.com/data-visuali...

We are partial to the "polychrome" palette when there are tens of single-cell clusters to distinguish, over the default ggplot colors. Even without a named handicap I can't distinguish the pinks or green-cyan-blue neighbors. cran.r-project.org/web/packages...

Important Announcement #zebrafish but not only

Thanks for citing Paul Tol's work. The palettes have nice colors, and it's easy to get the needed size: $ conda install bokeh $ python >>> import bokeh.palettes >>> for i in range(3, 24): ... print(bokeh.palettes.tol['TolRainbow'][i]) ('#1965B0', '#F7F056', '#DC050C') etc. personal.sron.nl/~pault

(pls amplify) Fresh off the press in the journal Nature today, groundbreaking work in immunogenetics. I have no doubts that the 4% holds some of the keys to cure cancer one day. Authors did a good job in other figures, we need journals to be more prescriptive about this @natureportfolio.bsky.social

Public Service Announcement: Check colorblind-compatibility in Illustrator! Under 'View', 'Proof Setup' you can selected a colorblindness type to view your image in that spectra. Click 'Proof Colors' after to remove filter. We chose pink/green, yellow/blue here for accessibility (PMID 38112643).

more thoughts on the TolRainbow palette for discontinuous/discrete categorical data (e.g for omics with >12 clusters, chromosomes, etc) If you look at the base of the pyramid and skip 19,21,23, you get 20 colors with a lot of range for both di- and trichromats

To be fair to Seurat it’s really applicable to all of ggplot2 but amplified by single cell visuals with lots of groups on single plot. scCustomize sets some better defaults that help with lots of the issues. :) samuel-marsh.github.io/scCustomize/...

Both versions look identical to me. Maybe one reason I am not much into single cell genomics that is not sequencing :)

(please amplify) 4% of scientists face an important barrier to an the ENTIRE FIELD of single-cell genomics and here is why

@science.org Sorry to be trolling already (this one is from 10.1126/sciadv.ado4167) but a lot of your papers are hard to read for 4% of scientists. Other journals like the New Phytologist issue guidance about figure color accessibility. You could also ask your editors to do better 💜thank you💚 Chloe

@jcellsci.bsky.social so happy to see you here! Hey sorry to be a troll but ... (spare the rod, spoil the child)

Hello, we issue guidance regarding figure accessibility here: nph.onlinelibrary.wiley.com/hub/journal/...

@natureportfolio.bsky.social The new paper on methane plumes in NatureGeo looks amazing but it's hard to read the figures. Could you issue editorial guidelines on color palettes to be more inclusive?

If you missed my live webinar on scientific #colour use, "Seeing the Unseen" ( #SpaceScience version), you can rewatch the complete recording here: youtu.be/QJK8BgihT_c #UseBatlow #DataViz #ISSIGameChangers 📊

💜💜💜

This deserves ETERNAL PRAISE. Journals and editors please pay attention 🤍

For the remaining 96% who are curious, here is the direct comparison. Minor difference in full spectrum view, major difference in protanopia and deuteranopia view. See alt text for Photoshop instructions.

@science.org 😢 please 💔

💜🖤💚🤍🧡💙

What you’re saying anytime you use red and green in your data visualisations. #dataviz #rstats

hello @newphyt.bsky.social 🌿 this works seems really cool but 🟠/🟢 🤷‍♀️, could you issue editorial guidance regarding figure prep puleez? I know these colors look like plants but if the data look like this, I can't become a phytologist 😭 💜💚 🧡💙 🤍🖤

💜💚

@biologists.bsky.social I love your journals, would even more if editors could enforce color accessibility. Thank you! Chloe 🧡💙 💜💚
