How did Persian tilework use floral patterns and shades of blue?

In Persian tilework, the integration of floral patterns and specific shades of blue was a hallmark of Iranian art, particularly in the decoration of mosques and architectural surfaces from the 13th to the 17th centuries.1

Floral Patterns

Persian tile designers frequently employed naturalistic floral motifs to create a gardenlike effect on walls, domes, and floors. Common depictions included:1
* Botanical variety: Artists rendered flowers such as the iris, rose, carnation, tulip, pomegranate, pine, and date.1
* Design structure: These floral elements were typically designed with delicately interlacing stems and were often contained within plain or patterned borders.1
* Stylization: While naturalistic in appearance, these designs often featured the same intricate, scrolling-vine systems found in Persian carpets, reflecting a shared aesthetic vocabulary between tilework and textile arts.21

Use of Blue

The use of blue was central to the Persian color palette, serving as a defining characteristic of the region's ceramic tradition.1
* Range of Hues: Designers utilized a full spectrum of blues, ranging from vibrant turquoise to deep, rich ultramarine.1
* Technical Application: These shades were often applied to tiles that combined floral and geometric designs. In some instances, blue glazes were used in conjunction with other techniques, such as lustre painting, to enhance the visual depth and richness of the surface decoration.134
