Hello Georgi,

Thank you for writing.

The form used by the RadColorDialog control exposes several properties with which you define which tabs will be visible. Please check the following documentation resource discussing these properties: RadColorDialog | Getting Started.

You can also access the RadPageView and add a new page to it, which can host a user control populated with colors as per your requirement. Please check my code snippet below: 

public Form1()
{
    InitializeComponent();

    this.radColorDialog1.ColorDialogForm.ShowBasicColors = false;
    this.radColorDialog1.ColorDialogForm.ShowCustomColors= false;
    this.radColorDialog1.ColorDialogForm.ShowProfessionalColors = false;
    this.radColorDialog1.ColorDialogForm.ShowSystemColors = false;

    ((RadColorDialogForm)this.radColorDialog1.ColorDialogForm).FormClosing += ColorDialogForm_FormClosing;
    RadPageView pageView = ((RadColorDialogForm)this.radColorDialog1.ColorDialogForm).RadColorSelector.Controls["radPageView1"] as RadPageView;

    RadPageViewPage corporatePage = new RadPageViewPage() { Text = "Corporate" };
    pageView.Pages.Add(corporatePage);
}

private void ColorDialogForm_FormClosing(object sender, FormClosingEventArgs e)
{
    // Read the selected corporate color.
}

I hope this helps. Please let me know if you need further assistance.
