This one explains what Synesthesia felt like. Originally published in "The A's Song", I've rewritten parts of it and presented it again wrapped in a nice and neat ribbon.
A is a light blue, like a robin's egg,
B is a strange color, maybe chocolate brown instead?
C is a sunny hue, always shining bright,
D is a tan brown, glimmering in the light,
E is a light green, like tree leaves in the sun,
F is a fox's tail, back legs arched, ready to run,
G is a pink, juicy, oval, purple grape,
H is a weird hue, it's all my mistake...
I is a pale blue, lifeless, gray, and cold,
J is a yellow-orange, it's an orange popsicle,
K is a deep purple, trusting and noble,
L is a blue gray, special to the core (and it's my favorite color!),
M is a night color, tints of hidden dark gray,
N is a black sky, hiding blue away,
O is a ring, shining in it's cage, (I couldn't find a rhyme)
P is a bright fruit, bursting in my mouth,
Q is a ink purple, the color of a shout,
R is a deep ancient color, lying in the canyon,
S is a curvy river, a good traveling companion,
T is a tree top, standing so tall,
U is a unicorn, sparkles and that all,
V is a orange purple, weird but unique,
W is a pointed umbrella, or a raven's beak,
X is a burst of colors, like the tie-dye rainbow, (I couldn't find a rhyme)
Y is a burst of lightning, grinning wickedly,
Z is a pitch black, charred to ashes and waiting to leave.
