VB里DrawLine指令里如何调用非标准色？又如何调用已经定义的颜色函数？

Question

非标准色：
RGB(255, 13, 0)
颜色函数：
ReDim color(10)
color(0) = RGB(255, 13, 0)
color(1) = RGB(255, 77, 0)
color(2) = RGB(255, 176, 0)
color(3) = RGB(247, 248, 0)
color(4) = RGB(176, 255, 0)
color(5) = RGB(75, 255, 0)
color(6) = RGB(0, 255, 176)
color(7) = RGB(0, 248, 247)
color(8) = RGB(0, 176, 255)
color(9) = RGB(0, 75, 255)

Answer 1

Dim myPen As Pen = New Pen(new Color(255, 13, 0), 2)
g.DrawEllipse(myPen, 30, 30, 90, 90) '在坐标为30,30 ~90,90 的范围内画一个红圆

画线用的brush也一样，换成
dim mysbrush1 as SolidBrush = new SolidBrush(new Color(xxx,xxx,xxx))
