    I don’t recommend it. Generally, you would want to use one hue for low to high values of sequential data but you can use 2 hues to increase contrast (e.g., light blue to dark blue, light yellow to blue). Blue and red are opposing colors and is more used as diverging scales where there are neutral tones (and values) in the middle (e.g., negative values, zero, positive values; blue-pale yellow-red). Here’s a nice resource on color schemes, https://colorbrewer2.org
