Color: The color palettes are predominantly monochromatic, using various shades of blue, sometimes accented with very subtle touches of pink or cream. This limited color range enhances the soft, illustrative feel of the styles and creates a calm and understated visual quality.
Lighting: The lighting is generally soft and diffused, with less emphasis on harsh shadows, which enhances the gentle and slightly melancholic feel of the styles. The use of soft gradients and a lack of strong highlights contributes to the overall calming visual aesthetic.
Design Technique: The design techniques employed emphasize fluid lines, soft edges, and a somewhat loose, illustrative approach. The styles look as if they are done with watercolor or ink, giving the characters a handmade and charming visual quality. This design technique lends itself to conveying emotion through delicate details and subtle textures.
