Review Comment:
   True ... We can use these theming tokens .... only problem was the alpha 
value is a bit low at anywhere between 0.04 to 0.15 
   
   function cellBackground({
     value,
     colorPositiveNegative = false,
     theme,
   }: {
     value: number;
     colorPositiveNegative: boolean;
     theme: SupersetTheme;
   }) {
     if (!colorPositiveNegative) {
       const fillColor = theme.colorFillSecondary; 
       const { r, g, b } = tinycolor(fillColor).toRgb();
       return `rgba(${r},${g},${b},0.2)`; 
     }
   
     if (value < 0) {
       return theme.colorErrorBg;
     }
   
     const successColor = theme.colorSuccess;
     const { r, g, b } = tinycolor(successColor).toRgb();
     return `rgba(${r},${g},${b},0.2)`;
   }
   
   This solution works though if we can rewrite the alpha value and since this 
completely depends on theming tokens we dont need to check if the theme is dark 
or not
