Detecting a pixel based on approximate color?

I am currently working on a AI for minesweeper and I am trying to detect the color of the numbers to see which number is there and I am having trouble finding the exact RGB code of it and when I print it it seems to change by slight amounts I am wondering if there is a way for to detect colors that are very similar to an RGB value? Thanks!

The solution was this:

    def check_clicked(self, rgb):
        ok = str(rgb).replace("(", "").replace(" ", "").replace(")", "").split(",")
        r = int(ok[0])
        g = int(ok[1])
        b = int(ok[2])
        r_min = 205
        r_max = 220
        g_min = 175
        g_max = 195
        b_min = 145
        b_max = 163
        r2_min = 225
        r2_max = 235
        g2_min = 185
        g2_max = 205
        b2_min = 150
        b2_max = 170
        if (r >= r_min and r <= r_max and b >= b_min and b <= b_max and g >= g_min and g <= g_max or r >= r2_min and r <= r2_max and b >= b2_min and b <= b2_max and g >= g2_min and g <= g2_max):
            self.set_properties(0)

explanation: I could not find the exact RGB value and sometimes they were inconsistent so instead I checked if the minimum/maximum fit in a certain range for each value and this solution worked and didn't create any false positives!

DISCLAIMER: This solution will only work for a single-channeled color.
