Create style function to return svg fill and colors

[iurynogueira]

          it is possible to reduce code repetition with function

const getCustomStyle = (border:string, backgroundColor: string, color:string, outline: string, fill: string) => ({
    border,
    backgroundColor,
    color,
    outline,
    svg: {
        fill,
    },
})
