When we want to chang the color of any field of Crystal Report we change the formatting formula of the field
and we do that >>right mouse button on Field>>FormatObject>>Font>>Color and press the formula button
in the Editor we put the code

If {dtStudents.Mark} > 1 Then

and the color of the field will change when the value is > 1

My Question is How we do that programmatically ?

You could use parameter fields[^].

In report, create a parameter field prmMark.

Change the formula something like as below
If {dtStudents.Mark} > @prmMark Then

Now, from from your code-behind send the value to parameter field prmMark. Sample code from above link.
private void button1_Click(object sender, EventArgs e)
    ReportDocument cryRpt = new ReportDocument();
    cryRpt.Load("PUT CRYSTAL REPORT PATH HERE\CrystalReport1.rpt");

    ParameterFieldDefinitions crParameterFieldDefinitions ;
    ParameterFieldDefinition crParameterFieldDefinition ;
    ParameterValues crParameterValues = new ParameterValues();
    ParameterDiscreteValue crParameterDiscreteValue = new ParameterDiscreteValue();

    crParameterDiscreteValue.Value = Convert.ToInt32(textBox1.Text);
    crParameterFieldDefinitions = cryRpt.DataDefinition.ParameterFields;
    crParameterFieldDefinition = crParameterFieldDefinitions["prmMark"];
    crParameterValues = crParameterFieldDefinition.CurrentValues;


    crystalReportViewer1.ReportSource = cryRpt;
