color changing pigment

KT-90572 is a cyan/red color changing pigment from Kolortek's KT-9000 Magic Chameleon Series — a multi-layer interference pigment built on natural mica with iron oxide and silica coatings. It delivers a clean angle-dependent shift between cyan and red, with a particle size range of 20–80 μm (D50: 25–35 μm), and performs best on dark or black substrates where the goniochromatic effect reads at full intensity.

This photochromic pigment shifts from a pale or clear state to a deep, rich color within one second of direct sunlight, then reverses indoors. Fine particle sizing makes it a workable printing pigment for inks, screen printing, and surface effects, with both clear-to-color and color-to-color options across purple, blue, red, green, and more. As a UV activated pigment, it stays dormant until sunlight or UV hits the substrate — no external power, no coating, just light.

Kolortek's chameleon pigment series covers a wide range of angle-dependent color shifting powders — from interference-based pearlescents to magnetic cat eye flakes — engineered for automotive coatings, cosmetics, and high-security printing. Each grade delivers a strong color flowing effect as viewing angle shifts, with collections spanning duochrome transitions, multicolor sequences, and holographic multichrome responses. Whether you're formulating a color shift pigment into nail gel, gravure ink, or a thermoplastic masterbatch, there's a specific product line built for that substrate.

KTP-32-BY is a thermochromic powder that transitions from vivid yellow to colorless at 32°C — a body-temperature-adjacent activation point that makes it well-suited for skin-contact applications like cosmetics and nail products. This heat sensitive pigment powder disperses cleanly in most coating and printing systems, and is also available in a BPA Free food grade version for product contact use cases such as cups and utensils. Formulators working in textiles printing, craft art, or specialty inks will find the 1–10μm particle range compatible with a broad range of application methods.

KT-MLC01 is a water-based thermochromic liquid crystal that cycles through twelve distinct colors — from black through copper, yellow, green, blue, and violet — across a 14℃ to 36℃ temperature window, making it one of the more visually dynamic options in the thermochromic category. Unlike single-transition thermochromic pigments, these mood liquid colors deliver a continuous chromatic shift in a single liquid formulation, suited for custom decorative paints, textile printing, and novelty cosmetic applications. Formulators looking to introduce live color-shift behavior into coatings or printed substrates will find the liquid format straightforward to incorporate.

Thermochromic pigments respond to temperature shifts by altering their visual appearance — either transitioning to colorless or shifting between distinct color states. In cosmetic formulations, this creates interactive products that react to skin temperature, ambient heat, or touch. For formulators working with lip products, nail lacquers, eyeshadows, or novelty cosmetics, these pigments offer a functional alternative to static color.

KT-PMC-02-YP is a Yellow/Purple photochromic pigment in the fine 1–10μm particle size range — a UV-reactive organic pigment that appears pale yellow in the absence of UV light and shifts to a deep purple within approximately one second of exposure to direct sunlight or UV illumination. 

KT-95102 is a fine particle size chameleon pigment (5–25μm) designed for applications requiring smooth surface finish and controlled color travel. It delivers a distinct blue-green to red shift, using multi-layer titanium dioxide coatings on transparent flake substrates. 

KT-90507 is an Orange/Cyan chameleon pigment in the 20–80μm particle size range — a color-shift pigment built on highly transparent flake crystals coated with titanium dioxide that produces a clear, angle-dependent shift between orange at the direct viewing angle and cyan at the oblique angle.
