The color picker does not completely adhere to theme colors, specifically for dark themes.

First, let me say that the color picker component looks and functions great. Bravo! However, there is a slight issue when it comes to theming. It is most noticeable when using a dark theme. I've created a stackblitz fork to show the issue. Notice that inside the picker the background colors aren't being used in several key spots. So the foreground color blends in.

I'm having the same issue:

I just use the default purple and green theme.

                    <mat-form-field>
                        <input matInput [ngxMatColorPicker]="picker"
                            [formControl]="colorControl">
                        <ngx-mat-color-toggle matSuffix [for]="picker"></ngx-mat-color-toggle>
                        <ngx-mat-color-picker #picker></ngx-mat-color-picker>
                    </mat-form-field>
