If you are looking for how to do this in Winforms, the simple answer is to create a new checkbox class that derives from CheckBox, then override the OnPaint method.

Here is an example on how to create custom looking checkboxes by overriding the OnPaint method:

public class CustomCheckBox : CheckBox
{
    public CustomCheckBox()
    {
        this.SetStyle(ControlStyles.UserPaint, true);
        this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
    }

    protected override void OnPaint(PaintEventArgs pevent)
    {
        base.OnPaint(pevent);
        if (this.Checked)
        {
            pevent.Graphics.FillRectangle(new SolidBrush(Color.Blue), new Rectangle(0, 0, 16, 16));
        }
        else
        {
            pevent.Graphics.FillRectangle(new SolidBrush(Color.Red), new Rectangle(0, 0, 16, 16));
        }
    }
}

It's very simple, but it gives you the basic idea.
