In case anyone else doesn't like the 2026.5 update to buttons. Here are the ways you can customize the colors again. Just change from the example colors I have given below...

(1) Theme, this will change the colors globally.

ha-switch-checked-background-color: "#737373"

ha-switch-checked-border-color: "#737373"

ha-switch-checked-thumb-background-color: "#02ad3e"

ha-switch-checked-thumb-border-color: "#02ad3e"

ha-switch-background-color: "#737373"

ha-switch-border-color: "#737373"

ha-switch-thumb-background-color: "#b0b0b0"

ha-switch-thumb-border-color: "#b0b0b0"

(2) Card Mod, changes colors for each dashboard card.

--ha-switch-checked-background-color: #737373;

--ha-switch-checked-border-color: #737373;

--ha-switch-checked-thumb-background-color: #02ad3e;

--ha-switch-checked-thumb-border-color: #02ad3e;

--ha-switch-background-color: #737373;

--ha-switch-border-color: #737373;

--ha-switch-thumb-background-color: #b0b0b0;

--ha-switch-thumb-border-color: #b0b0b0;

Hope that helps.
