Not able to change candlestick color (in Kline chart) using WithItemStyleOpts option

[vishnukumarkvs]

kline candlestick colors are not changing even though changing colors in WithItemStyleOpts option

Part of code

charts.WithItemStyleOpts(opts.ItemStyle{
		Color:        "#0F22C2",
		Color0:       "#C2BA0F",
		BorderColor:  "#0F22C2",
		BorderColor0: "#C2BA0F", 
		BorderWidth: 4,
	}),

As you can see, border colors are changing but not color and color0, which represent inside colors

Full code below:-

func Kline(company string, data []dto.OHLC) string{
	kline := charts.NewKLine()

	x := make([]string, 0)
	y := make([]opts.KlineData, 0)
	kd := ConvertOHLCtoKlineData(data)

	// Improvement: Uneccessary reverse order
	for i, j := 0, len(kd)-1; i < j; i, j = i+1, j-1 {
        kd[i], kd[j] = kd[j], kd[i]
    }
	for i := 0; i < len(kd); i++ {
		x = append(x, kd[i].Date)
		y = append(y, opts.KlineData{Value: kd[i].Data})
	}

	kline.SetGlobalOptions(
		charts.WithTitleOpts(opts.Title{
			Title: company,
		}),
		charts.WithXAxisOpts(opts.XAxis{
			SplitNumber: 20,
		}),
		charts.WithYAxisOpts(opts.YAxis{
			Scale: true,
		}),  
		charts.WithDataZoomOpts(opts.DataZoom{
			Type:       "inside",
			Start:      50,
			End:        100,
			XAxisIndex: []int{0},
		}),
		charts.WithDataZoomOpts(opts.DataZoom{
			Type:       "slider",
			Start:      50,
			End:        100,
			XAxisIndex: []int{0},
		}),
		charts.WithTooltipOpts(opts.Tooltip{Show: true}),
		charts.WithLegendOpts(opts.Legend{Show: true, Right: "80px"}),
	)

	kline.SetXAxis(x).AddSeries("kline", y).
		SetSeriesOptions(
			charts.WithMarkPointNameTypeItemOpts(opts.MarkPointNameTypeItem{
				Name:     "highest value",
				Type:     "max",
				ValueDim: "highest",
			}),
			charts.WithMarkPointNameTypeItemOpts(opts.MarkPointNameTypeItem{
				Name:     "lowest value",
				Type:     "min",
				ValueDim: "lowest",
			}),
			charts.WithMarkPointStyleOpts(opts.MarkPointStyle{
				Label: &opts.Label{
					Show: true,
				},
			}),
			charts.WithItemStyleOpts(opts.ItemStyle{
				Color:        "#0F22C2",
				Color0:       "#C2BA0F",
				BorderColor:  "#0F22C2",
				BorderColor0: "#C2BA0F", 
				BorderWidth: 4,
			}),
		)


	kline.SetXAxis(x).AddSeries("kline", y)
	f, _ := os.Create("kline_all.html")
	kline.Render(f)
	var b bytes.Buffer
    err := kline.Render(&b)
    if err != nil {
        log.Fatal(err)
    }

    return b.String()

}
