Bright

Why do all our memories fade out to pastels?
The dulling of the colors, the muffling of the bells?
Often we discover that a happening once dated
becomes a strain of music half-remembered, mostly faded,
and we labor to remember a life so full and vast
that fades down to a shadow relegated to the past.
Better to infuse the present with such light
that all its various colors shine out vividly and bright.

Prompt words are pastel, musical, labor, discover and why.
