In terms of color theory, both lilac and lavender fall within the purple family, but they have their differences.
A rich lilac tends to carry a pinkish hue or pinkish undertone, offering a warmer feel. You might describe pale lilac as having a light purple appearance, often associated with youthful innocence.
Lavender, conversely, leans toward a bluish tinge, giving it cooler hues and gray undertones.

Both pale purple colors are part of a sophisticated color palette. Even a deep lilac often reads as a softer, romantic shade, while a pale lavender color tends to appear more serene. In some lighting, lavender may even resemble a medium purple with subtle blue or gray undertones.
