Indigo is the bridge between blue and violet. In the kueh world, indigo appears in Kuih Seri Muka — a two-layered steamed cake with a glutinous rice bottom (dyed with butterfly pea, but left longer to become darker) and a silky pandan custard top.
Seri Muka is the queen of kueh. It requires precision: the rice layer must be pressed firmly but not too compact; the custard must be poured only when the rice is cool enough not to cook it prematurely; the steaming must be gentle, or the custard will bubble and crater. When done perfectly, the top layer wobbles like a calm sea, and the bottom layer holds it like a bed of indigo sand.
The book’s entry for Seri Muka is the longest. It includes stories of grandmothers who could tell if the kueh was ready just by tapping the steamer lid. Indigo, it explains, is the color of depth — of love that requires patience, of skill that cannot be rushed.
To make Seri Muka is to understand that beauty sits upon a foundation. No indigo sky is beautiful without the earth beneath it.

Based on the title "The Rainbow Kueh Book", it is highly likely you are referring to the popular cookbook by Singaporean author Angie Tang (often associated with the EGW Centre for Seniors). The book is a tribute to the art of making Kueh Lapis (Rainbow Layer Cake) and other traditional Nonya kuehs. the rainbow kueh book
Here is a helpful overview of the book, what makes it unique, and why it is a valuable resource for bakers.
Violet is the color of endings that are also beginnings. In the Rainbow Kueh Book, the final chapter belongs to the purple yam (ubi ungu). This tuber, with its rough brown skin and shocking violet flesh, becomes Kuih Ubi Ungu — a steamed, layered, or baked kueh depending on the region.
One beloved version is a simple steamed purple yam cake: mashed ubi ungu mixed with tapioca starch, coconut milk, and sugar, then poured into a tray and steamed until set. The color is so deep it looks like a bruise, but the taste is pure comfort: earthy, creamy, and faintly nutty. Sometimes it is rolled in grated coconut; other times it is cut into rectangles and served with a dollop of kaya (coconut egg jam).
Violet, the book says, is the color of mystery. It is the last color the eye sees before night falls. It contains both the warmth of red and the calm of blue. In kueh, violet reminds us that the rainbow is a circle — after violet comes red again. After the last bite of kueh, there is always the desire for another.
The book is printed on high-gloss paper that makes the steam look real. For visual learners, a QR code system links to 4K slow-motion videos showing how to slice a Kueh with a plastic oiled knife (to prevent sticking) without crushing the layers.
While the "Rainbow" Lapis is the star, the book typically covers a variety of traditional steamed and baked kuehs popular in Southeast Asia: Indigo is the bridge between blue and violet
Red is the first color in the book because red is the color of beginnings. In the Nyonya and Teochew traditions, the Ang Ku Kueh (Red Tortoise Cake) is a prayer made edible. Shaped like a tortoise shell — symbolizing longevity, protection, and the slow, steady accumulation of good fortune — this kueh is made from sweet potato dough and filled with yellow mung bean paste.
But red is not just a color here. It is an announcement. When a child turns one month old, or when ancestors are honored at Qing Ming, the red kueh appears. The dough is pressed into wooden molds carved with the character for "long life." The banana leaf beneath it is oiled just so, so that the kueh releases without tearing.
The Rainbow Kueh Book says: Red is the color of love that spans generations. It is the blush of a new mother’s cheeks, the ribbon on a gift for the gods.
To eat an Ang Ku Kueh is to taste soft, slightly chewy sweetness, with a gentle earthiness from the sweet potato. The red comes from natural beetroot or red yeast rice, never artificial coloring — because the ancestors, the book insists, can tell the difference.
Before diving into the pages of The Rainbow Kueh Book, it is essential to understand the subject matter. Unlike Western cakes that rely heavily on wheat flour and butter, Kueh is defined by "gluten-free" staples: rice flour, glutinous rice flour, tapioca starch, and coconut milk.
The "Rainbow" in the book’s title is not merely aesthetic. In Peranakan culture, color often signifies mood, season, and occasion. The vibrant pinks of dragon fruit, the deep blues of butterfly pea flower, and the sunny yellows of pumpkin are celebrated. The Rainbow Kueh Book does not rely on artificial syrups; instead, it dedicates an entire chapter to natural dyeing techniques, teaching you how to extract the most brilliant hues from your garden.
