Idea! You guys should write color poems! We could make it into a thread of poems about colors! :)

Black
Darkness, calm, quiet
Exhausted peace
Dark relief
Surrounding silence, muffling feelings
Hiding from the ruins of this life Nice rhythm! 

Green-Gray
Anguish, despair, suffocating pain
Slipping, falling, drowning
A lone scream in the dark
Stripped of all protection
No way out of the storms of this life I understand that using "of this life" is part of your "form" but do you think including it in only some of the verses would make it more...maybe powerful?  Just a thought.  I really like the images. 

Deep Green
Cool, resting, emptied
Drained of feeling
Alone, silent, numb
Resting in the silence of my mind
The calm in the wirlwind of this life This is beautiful!

Cold Green
Missing, longing, lonely
Hoping, wanting, wishing
Unfair, ungrateful, guilty
Dragging, ripping, tearing
The ache that won't leave this life The last line seems a little bit out of rhythm...what about "Aching and just living" or something (though I know you want to keep the pattern).  I like the alliteration (is that how you spell it?).

Medium Green
Fake, pretend, plastic
Illusions, smoke and mirrors
Practiced smile plastered on
Pain leaking from its tightly locked cage Really like it, very strong!
The act that glues together this life (this line, I would like much more as "the act that glues this life together", but I couldn't decide wether to stray from the patternish thing I had, or keep it) See Green-Gray. 

Warm Green
Content, peace, warmth
Family, friends, God
Happy glow that fills my soul
Rinding What do you mean here?, recieving, filling
The love that overflows in this life

Lime Green
Laughter, friendship, fun
Playing, whispering, giggling
Soaring on a cloud of happiness
Music filling sun-gold air
The joy that binds together this life (same thing as the medium green one)  Getting happier!   

Sweet Yellow
Pure, light, warm
Blissful smiling
Gentle laughing
Golden sunlight, soft breezes  Could this line be the end of the poem?
The contentedness that brings a smile to this life (I don't like my word choice here, it feels awkward compared to the lightness of the rest of it. Any suggestions?)

Sorry if I was picky!  Overall I think that this is a wonderful poem.  Maybe you could put in some more descriptions in the verses that tend to name a lot of general terms.  Post more poetry, Emma, this is great!!

Ooh, I like "Black" especially. I would, however, recommend trying to find a consistent syllabic structure, not necessarily a standard form, but something consistent enough that it doesn't just feel like you're listing adjectives willy-nilly. Doing that might also force you to fix some of the problems you had with awkwardness in your final lines.

This isn't about color per se, because I wrote it before reading this thread, but it makes frequent use of it (it was... supposed to be about clearing a field of grass, but somehow my weird obsession with battle imagery took over. I kind of like the juxtaposition though.):

Sunlight bubbles into the long dry grass

and gilds the whistling blades in shining gold.

Silver evaporates; crows scream in vile

disgust when fire bites at their ice-slicked wings.

Gold swords glitter; the ancient battlefield

awake once more to spill innocent blood.

Far away, the sound of slicing echoes

as the crows begin their reconnoissance.

War-torn air seethes with harsh and bitter smoke;

now the midday fire scorches the soldiers,

rains misery down on infinite ranks .

Sharp blades sever stalks and hiss with the heat.

Blood-saturated, the fallen lay piled

Together beneath the lowering sun

Now quiet blades gleam red in the twilight

And squalling crows alight on the rubble.

((I kind of tried to incorporate some of what I've learnt in AP English this year, and also Sondheim's "less is more" and "God is in the details" concepts, so if this came off as really pretentious that's probably why.)) 

Also, I love the color poem idea, and will probably write one or three soon.
