Solución:
En este ejemplo, he mostrado cómo establecer el color de fondo para las celdas, puede ejecutarlo para obtener el resultado:
from xlwt import Workbook
import xlwt
book = Workbook()
sheet1 = book.add_sheet('Sheet 1')
for i in range(0, 100):
st = xlwt.easyxf('pattern: pattern solid;')
st.pattern.pattern_fore_colour = i
sheet1.write(i % 24, i // 24, 'Test text', st)
book.save('simple.xls')
tuve este problema e hice muchas búsquedas
por fin encontré una buena y adecuada solución en: fuente de solución
funciona muy bien!
simplemente agregue esta clase a su proyecto y configure los colores de Excel:
class ColorMatcher(object):
"""

Prior to Excel 2007, Excel only had color
indexes, and that's all that xlwt supports. Maybe this will help,
though. It use a ColorMatcher that takes an RGB input and tries to
return the closest matching Excel color index:
