📝 Walkthrough

Walkthrough

DashboardLayout now accepts optional header color props and forwards them to the mobile BottomSheet. BottomSheet resolves header and close-button colors from explicit props and MUI theme values.

Changes

BottomSheet theme color handling

Layer / File(s)	Summary
DashboardLayout color prop wiring src/custom/DashboardLayout/DashboardLayout.tsx	DashboardLayoutProps adds optional header background and text colors. DashboardLayout forwards them to the mobile BottomSheet.
Compute and apply header colors src/custom/BottomSheet/BottomSheet.tsx	BottomSheet computes theme-based fallback colors and applies them to the header and close-button styles.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to b6e4a

The BottomSheet theme fallback and text-color change is localized, but it still appears to bypass the required shared theme export and semantic palette-token contract; merge is reasonable with explicit owner follow-up on that integration concern.

Hey @KhushamBansal , the main thing I noticed is that the text/icon color fallback is checking whether surface.tint exists, rather than the background that actually ends up being rendered.
For example, if someone passes headerBackgroundColor="#fff", we'd still get common.white for the text because surface.tint exists, which gives us white-on-white.
I think we should resolve the final header background first, then derive the default text color from that, while still letting an explicit headerTextColor override it. Also, we could resolve that text color once and reuse it for both the title and close icon instead of duplicating the logic.

@PARTH-TUSSLE Thanks for reviewing this PR. I have made the change.

Use the Sistent theme boundary and semantic color tokens.

BottomSheet imports MUI's useTheme directly and uses common.white and text.primary. Import useTheme from ../../theme and use the semantic text and icon tokens.

use it from ../../theme

[NSTKrishna]

it should be theme.palette.text.inverse : theme.palette.text.default

[PARTH-TUSSLE]

Thanks @KhushamBansal! The fallback to background.default, sharing the header foreground across the title/close icon, and prop forwarding in DashboardLayout look great.

One remaining contrast edge case: if someone passes a dark custom headerBackgroundColor (e.g. #121212), usingTint is false,
which defaults to text.default (dark text in light mode), resulting in low contrast.

We can use Sistent's readableTextColor helper from ../../theme so custom backgrounds adapt automatically while keeping explicit
headerTextColor as the priority override:

    import { useTheme, readableTextColor } from '../../theme';

    // ...
    const tint = theme.palette.surface?.tint;
    const finalHeaderBackgroundColor =
      headerBackgroundColor ?? tint ?? theme.palette.background.default;

    const defaultForeground = headerBackgroundColor
      ? readableTextColor(headerBackgroundColor, theme.palette.text.inverse, theme.palette.text.default)
      : tint ? theme.palette.text.inverse : theme.palette.text.default;

    const finalHeaderTextColor = headerTextColor ?? defaultForeground;

Could you also add a few quick unit tests for BottomSheet covering:
• Default surface.tint fallback
• Missing tint → background.default fallback
• Custom light / dark background contrast
• Explicit headerTextColor override

Other than that, this looks ready to go!
