IntelliJ Plugin: Contrast-Checked Editor Themes — Dark, Light and Low-Blue Night (WCAG 7:1 on every syntax color)

You look at this editor more hours than you look at any human face. A theme that is pretty at midnight and unreadable at 10am in a bright room is a theme you fight all day. These 4 themes are measured, not eyeballed. W3C WCAG 2.1 (2018), success criterion 1.4.6, asks for 7:1 contrast for normal text. Every one of the 44 text colors here — 11 syntax roles x 4 themes — measures at least 7.0:1 against its own background, and at least 4.9:1 against its own selection background, so a selected line stays readable instead of turning into a smear. Verify any pair yourself in any contrast checker; the hex values are printed below. Keyword, string, number, function, type, comment (muted) and error each carry a distinct hue in every theme, so you tell them apart by color and not by squinting. Two axes, four themes: Deep Dark - night / dim room, neutral grey Deep Light - daylight / bright office, neutral grey Amber Night - late night, blue channel pulled down Warm Paper - daylight, blue channel pulled down, paper-toned The role-to-color mapping is identical across all four, so switching by ambient light does not make you relearn what a string looks like.

Three steps, no account, no telemetry, works offline. A free browser color picker gives you colors; it does not give you a theme file the IDE will load, and it does not check the pair you just chose against the selection background you will actually be reading on. 7-day full refund. When the IntelliJ platform changes its theme keys in a new yearly release, the updated build lands in this same listing at no extra cost. Questions: one email, answered.
