JHU上传的Unofficial Transcript必须是黑白的吗？

网申系统上说上传的非官方成绩单需要是黑白的，不过它给出的理由说是因为担心彩色的太大导致上传不上去。但是我自己做的成绩单彩色扫描件(PDF)最终只有不到500KB，已经能上传上去了，是不是就不需要理会它的要求了？

不过它明确说"required"...估计还是得要黑白的么...

原文如下：
"You are required to upload a black and white scan transcript for each academic instance listed on your application. Do not attempt to upload a color scan of your transcript. Color scans are too large and cannot be accepted through this system. We also recommend that documents be scanned in at 150dpi. "

应该没影响把。。我也是传彩色的 毕竟他本意是怕你太大
