let g:atomic_underline = 1
let g:atomic_undercurl = 1

Hi, @Karmenzind!

I did some changes in february. Is it happening since the last update? (Have you been using the same config last month?)

[gerardbm]

I found the bug. Update the plugin and check if it works now.

BTW, keep in mind that modes are different now. I removed the cyan and red modes, and added more contrast options for the other modes. Space mode is dark with blue hue; Night mode is dark with orange hue; Light mode is light with orange hue. You can use one of this commands for GUI:

• (1) AtomicSpaceHC: sets the space mode (blue hue, dark background) in hard contrast (+4%).
• (2) AtomicSpaceMC: sets the space mode (blue hue, dark background) in medium contrast (default).
• (3) AtomicSpaceLC: sets the space mode (blue hue, dark background) in hard contrast (-4%).
• (4) AtomicNightHC: sets the night mode (orange hue, dark background) in hard contrast (+4%).
• (5) AtomicNightMC: sets the night mode (orange hue, dark background) in medium contrast (default).
• (6) AtomicNightLC: sets the night mode (orange hue, dark background) in hard contrast (-4%).
• (7) AtomicLightHC: sets the light mode (orange hue, light background) in hard contrast (+4%).
• (8) AtomicLightMC: sets the light mode (orange hue, light background) in medium contrast (default).
• (9) AtomicLightLC: sets the light mode (orange hue, light background) in hard contrast (-4%).

Or alternatively you can use a combination of this:

let g:atomic_mode = 6 | set background=dark

Modes 1 to 6 with background=dark; modes 7 to 9 with background=light.

The new version works fine. Thanks for your job. I've been using this colorscheme for years.

I removed the cyan and red modes, and added more contrast options for the other modes.

I love the red mode 😢

[gerardbm]

@Karmenzind, ok! Since I recalculated the colors with new scripts, I can easily create modes, so I will update vim-atomic to recover the red and the cyan modes; and I will probably add modes for green and purple colors ;)

[Karmenzind]

hahaha thanks!

[gerardbm]

Done! Now Atomic comes with 7 modes: 6 dark and 1 light.

Dark modes use a hue color every 60°:

• Space mode is blue (hue 240°)
• Onion mode is purple (hue 300°)
• Blood mode is red (hue 0°)
• Night mode is orange (hue 60°)
• Grass mode is green (hue 120°)
• Ocean mode is cyan (hue 180°)

Each mode has 3 contrasts:

• High contrast (HC), +4%
• Medium contrast (MC), 0 (default)
• Low contrast (LC), -4%

For the red color you can use the modes 7 (HC), 8 (MC) and 9 (LC).

[Karmenzind]

Thanks a lot! Already updated 😄

Hi @Karmenzind

I'm planning to change the base4 color, increasing the lightness at 75% (+7% more) and reducing the saturation at 20% (-10%). Do you also think it needs more lightness and less saturation? I probably need to test it in more screens.

For example, comparison between before and after this change:

What do you think about it?

[gerardbm]

I'm testing colors in two BenQ monitors and I still see the base4 quite good at 68% of lightness.

I liked the idea of having all the accent colors with the same contrast (65% and 68% respectively). However, base4 is important enough to have more lightness than others.

For example, I see it more useful when the most part of the text is not coding, like a website in w3m, or writing a markdown file, and it's the most used in the most cli-tools.

So I will think about it for some time.

[Karmenzind]

Hi Gerard
Personally I prefer the warmer theme. At first sight the 68% one looks more comfortable for me. But I'm not sure if it suits for coding. Maybe you should post a coding screenshot including various colors. After all it's what the theme mainly used for.

P.S. I usually change the theme according to the time and the room light. I wrote a function to choose random scheme every time I open the editor. As you can see, tokyonight and github provide several colorscheme options to set mode.

function! RandomSetColo(themes)
  let choosen_colo = a:themes[rand() % len(a:themes)]
  call SetColorScheme(choosen_colo)
endfunction

call RandomSetColo([
      \'NeoSolarized',
      \'atomic',
      \'blue-moon',
      \'boo',
      \'gruvbox',
      \'github_dark_default',
      \'github_light_default',
      \'nord',
      \'kat.nvim',
      \'kat.nwim',
      \'bluloco',
      \'tokyonight-night',
      \'tokyonight-storm',
      \'tokyonight-day',
      \'tokyonight-moon',
      \])

I don't know much about the mechanism of colorscheme. Is it possible/convenient for atomic to create options (for example atomic-blood, atomic-space, or more detailed atomic-blood-hc) like this? Then I can directly add them to this list without writing another function to shuffle atomic modes.

[gerardbm]

Ohh, I'm going to study this. I added 21 commands (AtomicBloodHC, AtomicLightLC, etc), but this way seems interesting as well.

About the colors, I think it would be good to change the 68% to only 70% for the light colors (10-16), add then +5% saturation, so they are easier to differenciate. The effect is that the dark colors and the bright colors have only a 5% of lightness difference and they are warm enough.

Then I reduce the saturation of the base colors to be more "readable" (-5% background, -15% base4). That's because if base4 has too much color, it seems that it loses contrast, even when it's the same, because the same saturation has this optical effect. So, saturarions were 30% and now would be:

• base1 25% (-5%),
• base2 25% (-5%),
• base3 20% (-10%),
• base4 15% (-15%).

There's not a lof of difference, but base4 looks more "white" and it seems to have a better contrast when it's the same (70%).

For example, before and after:

At the moment I'm improving the scripts to propagate the changes in one command xD

Edit: I improved the comment; this morning I didn't want to be late at job (I was in a hurry).

[gerardbm]

Comparing the values (relative luminance) with the old-atomic colors calculated with old algorithms, the bright colors were too bright (a relative luminance about 0.45), while dark colors were too dark (a relative luminance about 0.27).

With the new algorithms (hsluv), the relative luminance is 0.40 for the bright colors (-0.05) and 0.34 for the dark colors (+0.07). That means a Lightness of 70% for the bright colors and 65% for the dark colors. They have a contrast very similar and at the same time they are easy to differentiate.

This 70% is still darker than the old atomic bright colors. The test with 75% was too bright (relative luminance of 0.48, so it was brighter than the old atomic base4 color); I'm agree with you that it was too bright.

In resume, this color correction is balancing the contrast between dark and bright colors while keeping them easy to differentiate.

[Karmenzind]

Sorry for the late. Too busy these days looking for new job :(
The second picture looks more clear but a bit cold. I might prefer the first one. Maybe I am just too used to low contrast mode. So sorry that I can't give you more helpful feedback because these parameter details are too complicated for me and I'm not really sensitive to colors. 😂
BTW do you have any plan to create a light green mode (like RGB 199/237/204)?

[gerardbm]

Well, I'm not planning to do more than 1 light scheme, but if you want you could copy the script hsluv-pal-light-mc.py to hsluv-pal-green-md.py to make a different version. You only will need to install hsluv with pip (I used pip3.8), modify the base color (BA = 60) to BA = 120 (60 is orange, 120 is green). You should have to modify the output filenames to not overwrite the others, as a result, you get a values file, a new image with the colors, and values for the .Xresoures file:

Feel free to make new custom themes.

PS. I hope you find a new job! Good luck!
