for a primitive man, activity during the day meant ...请问这句话的意思，并分析句子结构，谢谢。

for a primitive man, activity during the day meant hunting and attacking, while he soon saw red as the color of bolld and anger and the heat that came with effort. and green is associated with passive defense and seof-protection.

你是不是两个单词写错了？ bolld应该是blood,seof-pro 应该是self-pro

对一个原始人来说，白天的活动就是打猎和攻击，而他很快就看到了红色，这是努力相伴而来的血液和愤怒以及热量的颜色。而绿色与被动防御以及自我保护相关联。
for a primitive man 状语
activity during the day meant hunting and attacking：during the day 修饰活动
blood and anger and the heat that came with effort. 定语从句。这个句子用 of 来修饰 red as the color.
green is associated with passive defense and seof-protection. 最基本的句型。

没看懂什么意思？
