c# - How can I set the RGB Color in font Using xssfworkbook npoi -

how can set rgb color in cell backgroudn using class xssfworkbook using npoi?

byte[] rgb = new byte[3] { 192, 50, 90 }; xssfcellstyle headercellstyle1 = (xssfcellstyle)wb.createcellstyle(); headercellstyle1.setfillforegroundcolor(new xssfcolor(new color(255, 255, 255))); 

i don't want use pattern:

titlestyle.bottombordercolor = indexedcolors.grey25percent.index; 

    solution of problem here      here define new xssfcolor , assign xssfcellstyle         var color = new xssfcolor(new byte[] { 0,255, 0 });  var rowstyle =(xssfcellstyle)wb.createcellstyle();  rowstyle.setfillforegroundcolor(color)
