How to do that Gradient Color Generator?

How can i generate 16 color. my starter color is "Red" and my terminal color "khaki". i have to insert 14 color. But it looks like gradient flow. Forexample color.Black does not come from red. Violent should come red from red.

You should be able to interpolate? This example is winforms, but the maths is identical - simply that with ASP.NET you'd have to write the color in the hex form. You may also (with ASP.NET) need to find the RGB values separately - but for info, Khaki (in winforms) is {240,230,140} (red is obviously {255,0,0}).

using System.Drawing;
using System.Windows.Forms;

static class Program {
    static void Main()
    {
        Form form = new Form();
        Color start = Color.Red, end = Color.Khaki;
        for (int i = 0; i < 16; i++)
        {
            int r = Interpolate(start.R, end.R, 15, i),
                g = Interpolate(start.G, end.G, 15, i),
                b = Interpolate(start.B, end.B, 15, i);

            Button button = new Button();
            button.Dock = DockStyle.Top;
            button.BackColor = Color.FromArgb(r, g, b);
            form.Controls.Add(button);
            button.BringToFront();
        }

        Application.Run(form);
    }
    static int Interpolate(int start, int end, int steps, int count)
    {
        float s = start, e = end, final = s + (((e - s) / steps) * count);
        return (int)final;
    }    
}
