Younger people do not seem to mind. This may be because Millennials grew up on blue light as they are native to technologies.
What must be looked at is the perspective of the outside sleeper or urban camper. Anyone sleeping in this light can experience SLEEP DEPRIVATION and an interruption in the natural rythms that regulate sleep and wakefulness.
Be aware of this. Sleep deprivation is very detrimental to any demanding alt lifestyle specifically for activists that need to keep their wits and composure about them...or us.
Also note that in the systems used by Cults (cult mind control or 'brain washing') sleep deprivation makes subjects much more easily suggestible. Behavior modification is much more possible then.
A solution might be to take melatonin the chemical the body produces naturally that causes sleep as these LED lights destroy it naturally occurring in the body.
Also try to get daytime sleep or naps. Sleeping in areas that have a natural landscape or familiar structures, old historical sites-a more comfortable, familiar energy for older people may be beneficial as well.
Interestingly this could be construed as an anti vagrant measure as people who are not aware of the effects consciously but still suffer from them may instinctively begin to stay away from such lighted areas for night time sleeping.
Housed people should also consider these effects and do more research on how they can interfere with sleep even for those sleeping inside.
The engineering article is VERY good I've linked here.
Instinctually people like the soft lights and we aren't wrong. Your instincts should be heeded not denied due to often mistaken popular opinion.
