A long time ago it was possible to damage CRT screens by using to large refresh frequencies (so the coils got overheated).
However since many years this is impossible, because the CRT have built-in electronics to detect the frequencies and show "unsupported mode" then.
Changing the color fastly is really no problem: It was never (the vertical refresh rate is always the same, even if you do not update a pixel) and it not a problem on flat panels.
I wouldn't say it would damage your monitor since there are programs that do this in an attempt to fix dead pixels. I can't remember any off the top of my head since I haven't used one in 3 years.
So it shouldn't do much, but then again you wouldn't be running this for extended periods of time, would you?
No worry, you're not working at low enough levels to damage any of your hardware (on any semi-sane operating system, at least -- but I don't know any that's crazy enough to let application SW working at such a reasonable abstraction level to damage a monitor;-).

很久以前，使用较大的刷新频率可能会损坏 CRT 屏幕（因此线圈过热）。
然而，多年来这是不可能的，因为 CRT 具有内置电子设备来检测频率并显示“不支持的模式”。
快速改变颜色确实没有问题：从来都不是（垂直刷新率总是相同的，即使你不更新像素），而且在平板显示器上这不是问题。

我不会说这会损坏您的显示器，因为有些程序会这样做以尝试修复坏像素。我已经记不起任何东西了，因为我已经三年没有使用过它了。
所以它应该不会做太多事情，但话又说回来，你不会长时间运行它，不是吗？

不用担心，您的工作水平不够低，不会损坏任何硬件（至少在任何半理智的操作系统上），但我不知道有什么疯狂到足以让应用程序软件在如此合理的水平上工作抽象级别会损坏监视器；-)。
