"too dark"?

i'm often told, upon beholding my artwork, that it's "too dark". i think it's because I am "too dark". I never take things that claim to be pure for what they appear to be, i always feel as if something is lurking there, in the shadows. still, i find an odd comfort in darkness. the quote, "...there is no sun without shadow, and it is essential to know the night." from the myth, Sisyphus, explains it best. you see, light can not exist without darkness, think about it, how would you detirmine how light something was if you never knew darkness? Basically, i believe there must be a balance. I find comfort in darkness, because without it, there is nothingness; that's what really scares me. i feel a deep connection with all that is dark, because it's different, it "pushes the envelope". some people say black is not a color, and it is only an absence of light. but for the people that dwell in it and find trueness in black it means so much. how can you tell someone they live their lives in an "absence"? and what good is a lifetime of days that are all the same?
