java当中显示紫色_在java中将深色变为亮色

我正在开发一个程序,我从图像的一部分中获取RGB值.我想去除颜色中的黑暗并使其变亮.我所做的是使用Color.RGBtoHSB然后获取亮度通道并将其设置为范围内的最高值,然后将HSB转换回RGB.但是,当我这样做时,颜色会完全改变.这是一个深红色的例子,它变成紫色,我用这个代码.

System.out.println("Before Conversion:");

System.out.println("R: " + rAvg + "\nG :" + gAvg + "\nB :" + bAvg);

Color.RGBtoHSB(rAvg, gAvg, bAvg, hsv);

hsv[2] = 100; //Set to max value

System.out.println("H: " + hsv[0] * 360 + "\nS: " + hsv[1] * 100 + "\nV :" + hsv[2]);

int rgb = Color.HSBtoRGB(hsv[0], hsv[1], hsv[2]);

System.out.println("After conversion");

Color color = new Color(rgb);

System.out.println("R: " + color.getRed());

System.out.println("G: " + color.getGreen());

System.out.println("B: " + color.getBlue());

输出：

Before Conversion:

R: 128

G :39

B :50

H: 352.58426

S: 69.53125

V :100.0

After conversion

R: 158

G: 126

B: 233
