Hello Abir,

Right now, RC has 3 themes:

1. Light
2. Dark
3. High Contrast
   In all 3 of them, the same red color has been used.

Regarding the Embedded Chat, this feature was not present earlier, so now we need to decide which color should be set from the theme. Although I think this red color is suitable for all the themes we currently have, I believe that the 'unread message' should feature an eye-catching color that’s easy to notice. I think the current red handles this well.

Abir and @Spiral-Memory, if you still think we should change it according to the theme, please let me know which color to select.

In all 3 of them, the same red color has been used.

Hi @dhairyashiil, unlike Rocket Chat, EmbeddedChat is not a standalone chat application. Its primary purpose is to be embedded within any website, allowing external developers to configure and customize it to their preferences.

For development purposes, it is presented inside Storybook. You can experiment with passing a theme object through the controls to define your designs. Additionally, you can explore the pre-built themes in the design variants. Instead of hardcoding colors, using colors from the theme object provides external developers with greater flexibility and control over customization.

Abir and @Spiral-Memory, if you still think we should change it according to the theme, please let me know which color to select.

Maybe you can use theme.colors.destructive or explore other colors in DefaultTheme.js and use lighten or darken to find a suitable shade in default mode and pre defined themes in storybook.

Thanks for the clarification! I understand that EmbeddedChat is for embedding in websites, not a standalone app like Rocket Chat. I'll explore the theme.colors.destructive, other colors in DefaultTheme.js 👍

Hello @abirc8010,

I tried setting the color from "destructive," but it didn't look good with the dark theme.

Later, I explored all the options in EmbeddedChat/packages/react/src/theme/, and after that,
I believe the most suitable color for the unread message divider should be 'theme.colors.foreground' as the foreground color will always be the opposite of the background color.

I checked it for both light and dark theme variants, and it looks good.

[Spiral-Memory]

In theme object, there is another key, commonColors or something similar, you can have the required color there.. if that color looks good in all themes provided..

[dhairyashiil]

Hello @Spiral-Memory,
I checked it, and the common colors have only two options across all the different variants: black and white.

Please refer to this image:

I believe that instead of setting it to black or white, setting it to "foreground" is a better option, considering all the different variants and their dark and light themes.

Below, I have attached a video where I demonstrate this across different variants and their dark and light themes:

unread.message.for.all.variants.in.light.and.dark.theme.2.mp4

[Spiral-Memory]

In commonColors, you please add your color as well, if your red color is consistent among all themes

[Spiral-Memory]

Or go with an error color..

[dhairyashiil]

@Spiral-Memory , Okay, how about this:

For all light themes, we will use the 'destructive' color, which is red or sometimes dark red.
For all dark themes, we will use the 'warningForeground' color, which is an orangish color.
