ColorPicker must have an option to revert to "Default color" (set color to null)

I was working with Kendo ColorPicker and ColorPalette and I created a widget for serenity. Everything works perfect, except at the constructor time, I do not know the color. This is how is working now...

        // [KendoColorPickerEditor(Columns=2, Palette = "['#000', '#333', '#666', '#999', '#ccc', '#fff']",Buttons =true,Preview =true)]
        //Palette : "basic" | "websafe" | "['#000', '#333', '#666'] or leave blank"
        [KendoColorPickerEditor( Buttons = true, Preview = true)]
        public String Color
        {
            get { return Fields.Color[this]; }
            set { Fields.Color[this] = value; }
        }

A refresh method is needed to reload the properties changed after constructor...like the "Color" property

It would be really nice, if you could combine the color picker with the palette. When the user then opens the color picker, he has the ability to select a custom color, but also to select quickly a predefined color. This would improve the users worklflow nicely.

Bug report

ColorPicker's value option is not taken with higher specificity.

Reproduction of the problem

1. Open the following dojo.
2. Set the value option of the widget.
3. Notice that the color is not changed despite having the configuration set.

Current behavior

Currently, the ColorPicker requires setting the value={color} attribute to the input element. However, value option does not alter the input's value despite being set.

This behavior is inconsistent with other picker widgets where the value option is taken more predominantly:

Expected/desired behavior

The ColorPicker should take the value option with higher specificity. Even in scenarios where the value={color} attribute is present on the input.

Environment

• Kendo UI version: 2024.1.319
• Browser: [all]

The error:

Try to edit color manually in preview configuration.

The color picker right now support only to display the HEX format or RGBA format. The color picker should also support RGB.

Our customer is used to using the RGB format and wants to use that format. The reason we do not want RGBA is that the color picker could use opacity and the selected color will be used in a report so opacity has to be always 1.

We tried to prevent the use of a different opacity but could not find a solution.

Bug report

The slider in the ColorPicker popup, when used in Mobile Application, is not styled correctly.

Reproduction of the problem

1. Open this example - https://dojo.telerik.com/EfiQUGad/10
2. Open the ColorPicker.

Current behavior

The slider is not styled.

Expected/desired behavior

The slider in the popup should be displayed appropriately.

Environment

• Kendo UI version: 2022.2.621

The Kendo UI ColorPicker's contrastTool shows the contrast ratios necessary to reach a certain accessibility level. While the current contrast ratio itself is localized, the thresholds for the AA and AAA levels are not. For languages like German, this means that for the ratio, "," is used as a decimal separator while the thresholds below use ".".
