@dendirthebeast quoted from when someone asked a similar question previously: "Well the cats in both Embers' and Ashes' covers are from official Warriors art, which is about the only way I can manage to get the same style. The background for Embers is also from official art, though Ashes is a stock photo from the interwebz. For the former, it just required some color adjustment to fit with the color scheme of the cover. The latter required a bit more manipulation, strategically blurring and recoloring until it at least somewhat resembled the background to a Warriors cover. Then you just add the circle (or square) for the cat face and adjust that accordingly. As for the title, I found an image with said title, preferably with a transparent background, and adjusted the colors. If you're familiar with a program called Artweaver, that's what I used. Otherwise, I assume Photoshop or Paint Tool Sai would have similar functionalities. Fire Alpaca may also, though it does lack some key features I did use (such as removing the white background on the title if I was unable to find a transparent one, which I believe was the case for Ashes)."
