no, its a huge spaghetti of new color variable names, and inherited by the new semantic naming…
this is the resource frontend/src/resources/theme/color/semantic.globals.ts at bbd9d8887dd4ff3193086bd3320c19c5b0e08397 · home-assistant/frontend · GitHub
but you have to look up in inspector which button uses which semantic when.
as Marcin told me
With the new button you can theme any of the variables here and change for example all fill primary quiet/normal/loud to a different color palete just chainging the “primary” in --ha-color-primary-xx to something else, and do the same for the on primary quiet/normal/loud

So just set all of these core primary colors. And the semantics are build up on them
--color-primary-05: #001721;
--color-primary-10: #002e3e;
--color-primary-20: #004156;
--color-primary-30: #006787;
--color-primary-40: #009ac7;
--color-primary-50: #18bcf2;
--color-primary-60: #37c8fd;
--color-primary-70: #7bd4fb;
--color-primary-80: #b9e6fc;
--color-primary-90: #dff3fc;
--color-primary-95: #eff9fe;
This is the beginning of our design system. We just use it for buttons now. But when we hopefully sometime use it on most parts of the software it will be really cool.
Which is what I did for all of my themes now like:
taking my original primary-color as the -40 variant and calculate from there
Dark blue:
# color palette
ha-color-primary-05: '#001321' # Near-black with a cool blue undertone
ha-color-primary-10: '#012744' # Very dark navy blue
ha-color-primary-20: '#06457a' # Deep, rich marine blue
ha-color-primary-30: '#0d60ad' # Bold cobalt-like blue
ha-color-primary-40: '#1675C9' # Vivid, primary-leaning sky blue (base)
ha-color-primary-50: '#3d90d6' # Lighter, softer azure tone
ha-color-primary-60: '#68a9e1' # Balanced light blue, good for highlights
ha-color-primary-70: '#92c2ec' # Gentle sky blue, ideal for backgrounds
ha-color-primary-80: '#c0ddf6' # Very light pastel blue
ha-color-primary-90: '#e1effb' # Pale icy blue, near-white
ha-color-primary-95: '#f1f8fd' # Almost white with a faint blue tint
and that worked up to b4, see 2025.8 Beta week! - #23 by Mariusthvdb
per b5 and now release, my buttons are all defaulted to the system default again, so I filed an issue to report that
edit
change the version numbers, I counted 6 betas, but we had only 5

added the ha- prefix in this post, just to not confuse readers
