Hi  

        TEXTURE       LIGHT           MEDIUM           DARK

            FINE           4             20                  8
            MEDIUM         5             23                 12
            COARSE        21             23                  4     

Using www.vassarstats.net/newcs.html
chi-square = 17.73
df = (3-1)(3-1) = 4
CV = .2718
there is evidence of association between color and texture for these limestones
