After ensuring transparency of your drawable file....

Try adding the following to the Notification.Builder pipeline:

.setColor(color);

color should be a resource int value, referring to a colour, like so:

int color = getResources().getColor(R.color.notification_color);

The non-deprecated way:

int color = ContextCompat.getColor(context, R.color.notification_color);

Please ensure to post all necessary code. Please post the code of R.drawable.logo_ntf as an update to your question. – Imdad Mar 25 '19 at 09:35
with other icons of any color it works.. its really strange – Giorgio Cafiso Mar 25 '19 at 09:36
OK it works. I just convert the image to black and white incrasing the sharpening. The problem could appear because the image contains gradients or is composed by many colors. – Giorgio Cafiso Mar 25 '19 at 09:45
Glad to hear it. – Imdad Mar 25 '19 at 11:26

For Android 5+, you have to create a transparent icon for notification small icon.

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    notification.setSmallIcon(R.drawable.icon_transperent);
    notification.setColor(getResources().getColor(R.color.notification_color));
} else { 
    notification.setSmallIcon(R.drawable.icon);
}
