Autumn Colour Palettes in Illustration 🍂

September always feels like a turning point in the year. The light shifts, evenings draw in, and suddenly everything looks a little moodier, warmer, and richer. For me as an illustrator, colour is often where the change of season first shows up in my work. Autumn brings with it deep berry tones, golden yellows, inky blues, and those flashes of neon or pastel that stop the palette from feeling too heavy.

This month, I thought I’d share a peek at how autumnal colours inspire my illustrations, with a few of my favourite pieces that carry the season’s mood in different ways.

Golden

This one’s all about warm golds, ochre, berry, and glowing reds—the classic autumn palette. I love how the golden tones catch the eye without overwhelming, creating a sense of warmth and light

Neon Nights

There’s something about autumn evenings that feels cinematic. This piece leans into inky black with pops of neon yellow and pink, capturing the glow of city lights against the longer nights.

Green Leopard Print 

Leopard print will always be a signature for Katsillustration, and this version was created with the cosier seasons in mind. The rich green backdrop makes it feel bold yet snug—perfect for autumn days and winter nights.

Autumn is a season of rich colours and cozy tones, and I hope these pieces give you a sense of that shift. To see more of my latest illustrations and seasonal work, check out Instagram, TikTok, or Pinterest—there’s plenty more to explore.
