Out of these to colours I like the first one more (for the same reasons as
BlueDays).
But let me go a bit off topic and make a suggestion... When I fought my problems by myself (SAD, agoraphobia, depression, insomnia- then I couldn't name them but I knew something was wrong with me) I used some unconventional methods - chromatherapy and aromatheraphy (still doing it). I couldn't afford for a specialist or anything like that. But I started with painting my room from a dark undefinable colour to a light yellow and blue and chose some suitable accessories also in light, suitable colours.
I don't want to deviate to much.. but just wanted to say it worked for me. It helped me fight the depression (I don't say this thing alone, but definitely helped to rise my spirit), helped me to learn to be optimistic (or maybe just get it out of me), sleep better and much more.
I think such dark colours as the second one may be a bit depressing, it make a room look cramped and cause a feeling of being closed and isolated. To personalise the room you always may choose suitable accessories.
So finally I just wanted to ask if you are sure you want your room to be that neutral and you don't want to have any more cheerful colour (I'm not saying orange or yellow cause these really may be too bright, but maybe blue or green). Whether it is your bedroom or living room you're gonna spend plenty of time there, and believe me or not the surrounding has a huge impact on one's mood. It's just my humble opinion.
So what do you think of this? hope I didn't make you even more indecisive.
