Hi

You can refer this below code for datagridview cell color.

Example:

DataGridView1.Item(ColumnIndex, RowIndex).Style.BackColor = Color
DataGridView1.Item(ColumnIndex, RowIndex).Style.ForeColor = Color

or

DataGridView1.CurrentCell.Style.BackColor = Color
DataGridView1.CurrentCell.Style.ForeColor = Color
