/*
White (#FFFFFF): White text will provide strong contrast against the dark background gradient and ensure readability. It's a classic choice for text on dark backgrounds.

Light Gray (#CCCCCC): If you want a slightly softer contrast, light gray can work well. It provides good readability without being as stark as white.

Pale Yellow (#FFFFCC): A subtle off-white or pale yellow can add warmth to the design while still offering enough contrast for readability.

Light Cyan (#E0FFFF): Light cyan can provide a cool and refreshing contrast against the dark background gradient.

Pale Orange (#FFE4B2): Another warm option, pale orange, can add a bit of vibrancy to the text while still maintaining readability.
