Is it possible to change background color of PDF in python FPDF?

I am tring to create a pdf with a colored background in python using FPDF.

Is there a way to change the background color from white to some other color? Or do I have to insert colored cells to fill the entire pdf?

from fpdf import FPDF

pdf = FPDF()
pdf.add_page()
pdf.set_font("Arial", size=12)
pdf.set_fill_color(248,245,235)
pdf.cell(200, 40,'Colored cell', 0, 1, 'C', fill=True)
pdf.output("test.pdf")
