description: Personalize Sencho's look. Choose a visual style, tune readability and the security charts, pick a theme and accent, swap the interface and data fonts, and set the text size. Every choice is saved to the current browser.

**Settings → Appearance** is where you make Sencho look the way you want. Choose between the Calm and Signature visual styles, dial in readability, set how the security charts are colored, pick a theme and accent, choose the interface and data fonts, and scale the text. A live preview reflects every change as you make it.

Below are the Security Visualization chart-palette control with Muted selected, and the Readability section with its mode toggle, header-style control, and contrast slider." />
</Frame>

Several of these controls are also one click away from anywhere in the app: the **palette button** in the top bar, between the search and notification icons, opens a quick switcher for the theme mode, accent, visual style, readability, and text size. The sliders for contrast, borders, and glow stay in this Settings section.

  Appearance choices are saved to **this browser only**. They follow you across tabs on the same browser, and every device remembers its own look. Nothing here changes what other operators see.

## Visual style

The **Visual style** is the master switch for how intense the interface feels:

- **Calm** (the default) keeps headings upright in the interface font, colors the security charts with a muted palette, and reduces material effects. It is the most readable setting.
- **Signature** uses italic Instrument Serif headings and the fully saturated chart palette for a more editorial look.

Picking a style sets the heading, chart, and effects controls below in one move. You are free to adjust any of them afterward to build your own combination. When **Readability mode** is on it overrides these until you turn it off.

## Readability

**Readability mode** is a single switch for the most legible result: upright headings, the muted chart palette, reduced effects, and a small contrast lift, all at once. While it is on, the heading and chart controls are locked to their calm values. Turn it off to set them by hand.

- **Header style** chooses **Clean** (the upright interface face) or **Signature** (italic Instrument Serif). Decorative moments such as the Sencho wordmark stay in the serif either way.
- **Contrast** is a master control that spreads the page tone, every border, and the text tiers together. Higher contrast darkens the page, brightens borders, and crisps up secondary text. Pairing high contrast with the OLED theme gives the sharpest reading on a true-black panel.

## Security visualization

The **Chart palette** sets the colors used on the Security page charts:

- **Muted** desaturates the severity colors so critical, high, medium, and low read as a calm progression with no jarring color pairings.
- **Heat** is a single warm ramp from a deep red through amber, with no competing hues.
- **Signature** is the saturated severity set.

## Motion & effects

- **Reduced effects** flattens card bevels, the accent glow, and chart gradients for a calmer, flatter surface.
- **Ambient glow** sets the intensity of the soft, accent-tinted glow behind the page. Slide it to zero for a completely flat background. (Reduced effects already dims it.)

## Theme

The **Mode** control sets the overall surface palette:

- **Dim** (default) is a raised charcoal. Cards and panels sit clearly above the page without going fully black.
- **OLED** is true black, ideal for power-saving panels. Borders stay visible so cards never merge into the background.
- **Light** is the bright theme, with the same directional, opaque borders inverted for a white surface.
- **Auto** follows your operating system, switching between Dim and Light as your OS does, and re-resolving live when the OS flips.

The **accent** is Sencho's one data color. It drives charts, sparklines, progress bars, focus rings, active states, the masthead and sidebar rails, and the ambient page glow, so changing it recolors the whole product cohesively. Eight well-spaced hues are available: **Cyan** (the default and the signature), **Blue**, **Violet**, **Magenta**, **Orange**, **Amber**, **Lime**, and **Steel** (a deliberate near-neutral). Status colors (green for healthy, amber for warning, rose for error) stay constant regardless of accent so state always reads the same.

**Border brightness** lifts or softens every hairline on its own, so the separation between cards reads exactly how you like it. A **Reset fine-tune** button returns contrast, border brightness, and ambient glow to their defaults.

## Typography

Sencho uses three type contexts. The interface and data faces are yours to change; the heading style follows your Visual style choice.

</Frame>

- **Interface font** sets the sans face used for body text, labels, navigation, and buttons. Choose **Geist** (default), **IBM Plex Sans**, or **Hanken Grotesk**.
- **Data font** sets the monospace face used for the terminal, stat values, codes, and timestamps. Choose **Geist Mono** (default), **IBM Plex Mono**, or **Fira Code**.
- **Text size** scales the entire interface from a single root multiplier. In Settings this is a continuous slider (default `1.00×`); the top-bar quick switcher offers **S / M / L / XL** presets. Both stay in sync.

## Display

The **Display** group holds the remaining per-browser preferences:

- **Density** switches between **Comfortable** (roomy rows, the default) and **Compact** (tighter rows and tiles that fit more on screen for dense dashboards).
- **Top navigation labels** shows text labels beside the top navigation icons. Turn it off for an icon-only bar; the destinations stay reachable by hover tooltip, accessible name, and the command palette. On the phone layout the navigation always keeps its labels. With labels off, **Top navigation alignment** chooses whether the icon-only bar sits to the left or centered.
- **Log chip color** controls how service chips are colored in log views. **Unified** uses the accent color for all service chips. **Per service** assigns each service a stable label color for faster visual scanning when following multiple services at once.

Deploy-progress behavior and the diff-preview-before-save step are stack workflow preferences, so they live in **Settings → Infrastructure → Stacks**, not here.

## Troubleshooting

<AccordionGroup>
  <Accordion title="My theme didn't carry over to another device or browser">
    Appearance is saved to the browser you set it in, not to your account. Every browser and every device keeps its own look on purpose, so a compact laptop setup never forces the same rhythm on a large desktop. Open Sencho on the new browser, pick your theme, accent, fonts, and density again, and they persist there from then on.
  </Accordion>
  <Accordion title="My appearance reset to the defaults">
    Sencho reads your choices from this browser's local storage. Clearing site data, signing in from a private or incognito window, or a browser that blocks local storage drops you back to the defaults: **Dim** mode, **Cyan** accent, **Geist** and **Geist Mono** fonts, **1.00×** text size, and **Comfortable** density. Re-pick what you want and it sticks for that browser.
  </Accordion>
  <Accordion title="Will changing my accent or theme affect other operators?">
    No. Appearance is local to your browser and is never sent to the server or shared. Other operators, and your own other devices, keep whatever look they set. There is no shared or organization-wide appearance setting; each person chooses their own.
  </Accordion>
  <Accordion title="The quick switcher doesn't have the contrast, border, and glow sliders">
    The top-bar palette button is a fast path for the most-used controls: mode, accent, visual style, readability, and text size. Contrast, border brightness, and ambient glow live here in **Settings → Appearance**, where the live preview reflects each change as you drag. Both paths write to the same per-browser storage, so a change in one shows up immediately in the other.
