Dynamic color formatting issue

Hi,

here is the Scenario ;

if value gretaer than 1 then green,

if between 0,95 and 1 then yellow

if less than 0,95 then red

customer enter target value for example X (in pic you can see) = 50 then

in case of Foods -> 46/50 = 0,92 

                High Tech -> 48/50 =  0,96

                Lighting -> 51/50 = 1,02

                Motorcycles -> = 54/50 = 1,08

                Pumps -> = 59/50 = 1.18

i have no idea how to manage this. i think relevant script/code should be  embedded in Button component.

Help please !
