setColor small icon notification android - android

I change the top color of the icon and the app name by using setColor method of the NotificationCompat.Builder, The problem is that the displayed color doesn't match the provided one as it gets darker in the notification.
my color is #21bbe6
I did find out Android N notification title and icon color is darker, but I still don't understand why, and how to deal with it.

Google decided to restrict acceptable colors in Notification when using setColor.
It's undocumented!

How can we use multi color icon in android notification icon

I have already tried with transparent background, it's working fine but I need more than 1 color in the notification small icon.
When I am trying to get results find whatever color we use that will change by icon color what we give in our code only transparent color is always transparent.
I have tried custom layout notifications but I got stuck with android 11 some devices work fine but some devices show a grey square icon.
I want a notification icon with multi-color in the status bar and when we expand notifications.
As of android V5.0.0 i.e target sdk version 21, android will always tint your notification icon on the status bar. On Scrolling down the notifications on your lock screen in the newer version you can show a custom icon that can be of any color but on the status bar you wont be able to show multi color icons.

How to support multiple colors (more than two color) for Android Notification icon?

I am working on Android app (API level >23). And I have to
support Notification.
And my notification icon is supported more than two colors.
If I use that icon then icon displays in grey in notification
pannel.
So I have created background transparent and completly white icon
and set color dynamically.
But I am able to set only one color (setColor()).
So my question is :-
How to support multiple colors (more than two color or color gradients) for Android Notification icon?
Note :- I have taken reference of Android Push Notifications: Icon not displaying in notification, white square shown instead
Thanks for support in advance.
If your app targets SDK 21+ the system will always tint your notification icon
white when it's displayed in a dark status bar
dark grey when it's displayed on a light status bar (API 23+)
dark grey when it's collapsed at the bottom of the notification shade
the color you set when it's part of a notification in the notification shade (API 24+, before that you'd have a white icon over a colored circle as the default large notification icon)
You have no control over the color other than what's described above.
But you can work with alpha channel. You can achieve different degrees of white/dark grey/color in your icon.
No, there's no other way. Pass this on to your designer and management.
Android 5.0 Behavior Changes
Notifications
Material design style
Update or remove assets that involve color. The system ignores all non-alpha channels in action icons and in the main notification icon. You should assume that these icons will be alpha-only. The system draws notification icons in white and action icons in dark gray.

Notifications
Make sure your notifications take these Android 5.0 changes into account. To learn more about designing your notifications for Android 5.0 and higher, see the notifications design guide.
Material design style
Notifications are drawn with dark text atop white (or very light) backgrounds to match the new material design widgets. Make sure that all your notifications look right with the new color scheme. If your notifications look wrong, fix them:
Use setColor() to set an accent color in a circle behind your icon image.

It seems that this color is taken based on app colors icon - probabbly most frequently used color.

Notification icon on status bar is coming as white box

How do i customize the notification icon on the status bar in my phone running Android 5.0. It always comes as a white box(image attached).
The notification icon in the notification bar comes colorful as expected but the status bar icon comes as white square box.l
android 5.0 uses the icon that you give him and puts a color filter on it. If you want to see your icon, you must use an icon with transparency (png). I advice you to set another icon other than the icon of your application and remove the rectangle with rounded border.
There is some restrictions for notification icons. And also Lollipop doesn't show exactly what you set. It flatifies the notification icons and also suggest you to use flat style icons.
