Iridescent(彩虹)是林肯公园第4部专辑《A Thousand suns》中的12首歌,[1]2011年4月被定为电影《变形金刚3》的主题曲，并将重新拍摄MV。
在林肯公园的官方网站上，乐队发表了一份声明，该声明中写道：“《Iridescent》这首歌曲在我们的现场表演中是观众最喜欢的歌曲之一，所以我们很高兴导演Michael Bay能够使用我们的这首歌曲。”
《彩虹光芒》是收录在林肯公园2010年专辑《烈日千阳》(A thousand Suns)中的一首歌曲，旋律舒缓，歌词简练，悲伤之中透露着希望，整体给人一种比较忧伤的文艺范的感觉，在林肯公园的歌曲中，算是非常抒情的一首。在为《变3》重新编曲的混音版本中，虽然着重加强了节奏，但与此前气势磅礴、金属感极强的《What I' ve done》与《New Divide》相比，《彩虹光芒：混音版》还是显得比较抒情，给人一种完全不一样的感觉，不知道这是不是意味着《变3》会在整体风格与情绪基调上，相较前两部有不小的变化。
中英双语歌词：
《Iridescent( 虹)》
[Mike]
When you were standing in the wake of devastation
当你站在灾难后的遗迹前
When you were waiting on the edge of the unknown
当你等待着不可预测的变化
With the cataclysm raining down
此时灾难即将如大雨般落下
Insides crying "save me now"
你的内心呐喊着“拯救我”
You were there impossibly alone
却无法忽视万分孤单的处境
[Chester]
Do you feel cold and lost in desperation
是否你感到冰冷无助?
You build up hope but failure's all you've known
你满怀希望但最终充满绝望
Remember all the sadness and frustration
记住这所有的悲哀和沮丧
And let it go let it go
然后让时光冲刷掉这些不快
[Mike]
And in the burst of light that blinded every angel
在足以使天使失明的爆裂的强光下
As if the sky had blown the heavens into stars
天空支离，天堂破碎
You felt the gravity of tempered grace falling into empty space
你发现神的恩赐坠入虚无
No one there to catch you in their arms
没有人能做你的保护人
[Chester][Chours]
Do you feel cold and lost in desperation
是否你感到冰冷无助?
You build up hope but failure's all you've known
你满怀希望但最终充满绝望
Remember all the sadness and frustration
记住这所有的悲哀和沮丧
And let it go let it go
然后让时光冲刷掉这些不快
Let it go
让这些不快逝去
4版本二歌词
《Iridescent( 虹)》
When you were standing in the wake of devastation
当你站在苏醒的灾难前
When you were waiting on the edge of the unknown
等在不可知的界线上
With the cataclysm raining down
知道毁灭将瓢泼而至
Insides crying "save me now"
你的灵魂哭喊着救我
You were there impossibly alone
但你孑然一人
Do you feel cold and lost in desperation
你是否感到冰冷无助?
You build up hope but failure's all you've known
你徒劳地造着希望 但徒劳便是你的所有
Remember all the sadness and frustration
记住这所有的悲哀和沮丧
And let it go let it go
然后放手
And in the burst of light that blinded every angel
在让所有天使失明的爆裂光亮里
As if the sky had blown the heavens into stars
天堂破碎成星辰
You felt the gravity of tempered grace falling into empty space
你感到上帝的恩泽坠入虚无
No one there to catch you in their arms
而没人能抱你入怀
Do you feel cold and lost in desperation
你是否感到冰冷无助?
You build up hope but failure's all you've known
你徒劳地造着希望 但徒劳便是你的所有
Remember all the sadness and frustration
记住这所有的悲哀和沮丧
And let it go let it go
然后放手
