推荐答案

您可以将当前颜色压入属性堆栈，更改颜色，绘制文本，然后弹出堆栈以恢复原始颜色:

You could push the current colour onto the attribute stack, change the colour, draw the text, and then pop the stack to restore the original colour:

glPushAttrib(GL_CURRENT_BIT);
glColor3f(...);
// Draw your text
glPopAttrib(); // This sets the colour back to its original value
