It has distinct colors. You can read thrombus here and make a custom color sequence https://arxiv.org/abs/2107.02270.\n\n_Originally posted by @timhoffm in https://github.com/matplotlib/matplotlib/issues/27851#issuecomment-2888117779_\n\n@timhoffm That was my memory (and if I had dug back further into Issue https://github.com/matplotlib/matplotlib/issues/9460 I would have seen https://github.com/matplotlib/matplotlib/issues/9460#issuecomment-875185352 and it would be obvious, so thanks for the reminder on that), but it seemed weird given the discussions we had with @tacaswell on https://github.com/mpetroff/accessible-color-cycles/issues/1 that we didn't add the 6 and 8 color sequence at the same time in PR https://github.com/matplotlib/matplotlib/pull/27851 so I thought I might be mistaken.\n\n\u003cdetails\u003e\n\n\u003csummary\u003eThe colors for the 6, 8, and 10 sequences:\u003c/summary\u003e\n\nReplicating @mpetroff's https://github.com/matplotlib/matplotlib/issues/9460#issuecomment-875185352 here for easier access:\n\n\u003e I finally finished the manuscript and have the [pre-print posted](https://arxiv.org/abs/2107.02270) (and [the analysis code](https://github.com/mpetroff/accessible-color-cycles)). The final results are:\n\u003e \n\u003e Six color: `#5790fc`, `#f89c20`, `#e42536`, `#964a8b`, `#9c9ca1`, `#7a21dd`\n\u003e \n\u003e ```\n\u003e [\"#5790fc\", \"#f89c20\", \"#e42536\", \"#964a8b\", \"#9c9ca1\", \"#7a21dd\"]\n\u003e ```\n\u003e \n\u003e Eight color: `#1845fb`, `#ff5e02`, `#c91f16`, `#c849a9`, `#adad7d`, `#86c8dd`, `#578dff`, `#656364`\n\u003e\n\u003e ``` \n\u003e [\"#1845fb\", \"#ff5e02\", \"#c91f16\", \"#c849a9\", \"#adad7d\", \"#86c8dd\", \"#578dff\", \"#656364\"]\n\u003e ```\n\u003e\n\u003e Ten color: `#3f90da`, `#ffa90e`, `#bd1f01`, `#94a4a2`, `#832db6`, `#a96b59`, `#e76300`, `#b9ac70`, `#717581`, `#92dadd`\n\u003e\n\u003e ``` \n\u003e [\"#3f90da\", \"#ffa90e\", \"#bd1f01\", \"#94a4a2\", \"#832db6\", \"#a96b59\", \"#e76300\", \"#b9ac70\", \"#717581\", \"#92dadd\"]\n\u003e ```\n\n\n\u003c/details\u003e\n\n\u003e make a custom color sequence\n\nIs there a reason to not support the 6 and 8 sequence as well? I assume not, given that [the style sheets](https://matplotlib.org/stable/gallery/style_sheets/style_sheets_reference.html) have 8 color styles.
