If you want to change the color of the text itself (i.e. the ForeColor property) in a single textbox:

private void button1_Click(object sender, EventArgs e)
{
ColorDialog cd = new ColorDialog();
cd.AnyColor = true;
cd.AllowFullOpen = false;
cd.SolidColorOnly = false;
DialogResult dr = cd.ShowDialog();
if (dr == DialogResult.OK)
{
textBox1.ForeColor = cd.Color;
}
}

or to change the foreground color of all textboxes on the form, then replace this line:

textBox1.ForeColor = cd.Color;

with this:

RecursiveChangeForeColorTextBoxes(this.Controls, cd.Color);

and add this method:

private void RecursiveChangeForeColorTextBoxes(Control.ControlCollection cc, System.Drawing.Color color)
{
foreach (Control ctrl in cc)
{
if (ctrl is TextBox)
{
TextBox tb = (TextBox)ctrl;
tb.ForeColor = color;
}
else if (ctrl.HasChildren)
{
RecursiveChangeForeColorTextBoxes(ctrl.Controls, color);
}
}
}

If it's just one textbox (say textBox1) whose background color you want to change:

private void button1_Click(object sender, EventArgs e)
{
ColorDialog cd = new ColorDialog();
cd.AnyColor = true;
cd.AllowFullOpen = false;
cd.SolidColorOnly = false;
DialogResult dr = cd.ShowDialog();
if (dr == DialogResult.OK)
{
textBox1.BackColor = cd.Color;
}
}

If you want to change the background color of all textboxes on the form, then replace this line:

textBox1.BackColor = cd.Color;

with this:

RecursiveChangeBackColorTextBoxes(this.Controls, cd.Color);

and add this method:

private void RecursiveChangeBackColorTextBoxes(Control.ControlCollection cc, System.Drawing.Color color)
{
foreach (Control ctrl in cc)
{
if (ctrl is TextBox)
{
TextBox tb = (TextBox)ctrl;
tb.BackColor = color;
}
else if (ctrl.HasChildren)
{
RecursiveChangeBackColorTextBoxes(ctrl.Controls, color);
}
}
}
