The Method

How a personal color analysis session actually works.

Personal color analysis is often presented as something subjective, an aesthetic judgment, a vibe-based read. It is not. At Color Analysis Studio PH, every session follows a defined four-step method built on Korean color industry standards, anchored by objective skin-tone data, and validated against the KCI (Korea Color Identity) 12-season system, patented in Korea by the Korea Fashion Psychology Institute.

This page documents the method in detail, names the tools we use, and links the science we draw from, so you know exactly what happens in the room before you book.

The Color Analysis Studio PH 4-Step Method, defined

Definition
The Color Analysis Studio PH 4-Step Method is a sequence of one objective measurement followed by three calibrated visual steps that together identify a client's exact season within the KCI (Korea Color Identity) 12-season color system, patented in Korea by the Korea Fashion Psychology Institute.
  1. 01

    Colorimetric reading

    A professional colorist instrument, a colorimeter or a spectrophotometer depending on the session, takes a digital measurement of your skin tone directly from your face. The instrument records the CIELAB color values of your bare skin under controlled lighting, removing the variability of natural light, phone cameras, and seasonal tan. This reading becomes the data foundation for everything that follows.

  2. 02

    Visual assessment of eye and hair color

    Your analyst confirms the instrument reading with a trained visual assessment of your eye color, hair color, and how they interact with your skin under controlled studio lighting. This step catches edge cases the instrument alone cannot, particularly clients whose eye and hair contrast pulls them into a neighboring season.

    Tool: Calibrated studio lighting  ·  Output: Confirmed temperature + value range

  3. 03

    Fabric draping

    Fabric swatches from the KCI (Korea Color Identity) 12-season library are placed near your face one at a time, light to dark, warm to cool, muted to vivid. Your analyst observes how each color affects the appearance of your skin, eyes, and overall facial harmony, narrowing in until your exact season is unmistakable. This is the longest step of the session and the one most clients describe as the moment they "see it for themselves."

    Color reading and palette delivery

    Your season is named, your printed palette card is presented, and your analyst walks you through how to apply your colors to wardrobe, makeup, hair color, jewelry metals, and perfume choices. You leave with access to MyColorPass, the studio's companion app where your recommendations live, so the framework stays with you long after the session ends.

Why this method works

It starts with data, not vibes. Most personal color content online is purely visual judgment, which is why two analysts can place the same person in two different seasons. The instrument-measurement step removes that ambiguity. Skin tone is a measurable physical property, and our session begins by measuring it.

It uses the KCI 12-season system, not the older 4-season one. The four-season model (spring, summer, autumn, winter) is a 1980s simplification that was never accurate enough for non-Caucasian skin. The Korean color industry refined it into a 12-season system in the 2000s, with three sub-types per season, codified as the KCI (Korea Color Identity) system patented by the Korea Fashion Psychology Institute. Every Color Analysis Studio PH client is placed within that 12-season framework.

It is reproducible across both studios. Both BGC and Angeles use the same equipment, the same lighting setup, the same swatch library, and the same trained analyst. A client who books in BGC and a client who books in Angeles get the same standard of session, with the same protocol.

It is built for Filipina and Asian skin. The Korean 12-season system was developed specifically around Asian features, then refined in Korea over two decades. The Western 4-season model still in use elsewhere was calibrated to Caucasian skin and tends to default deeper skin tones into "Autumn" by mistake. We chose the Korean method because it reads Filipina, morena, and mestiza skin accurately — not as an afterthought. Read more about color analysis for morena skin →

Common questions about the method

How is this different from an AI app or phone-camera color analysis?

AI and phone-camera tools rely on consumer-grade RGB images, which are heavily affected by ambient lighting, white balance, screen color, and camera processing. Two photos of the same person can produce two different season recommendations. Our method begins with calibrated professional colorist instruments, colorimeters and spectrophotometers, measuring CIELAB values directly from your skin, eliminating that variability before any visual judgment happens.

Why use the KCI 12-season system specifically?

KCI (Korea Color Identity) is the 12-season personal color system patented in Korea by the Korea Fashion Psychology Institute. It is an evidence-based refinement of the older 4-season model, with three sub-types per season (e.g., light spring, clear spring, bright spring). That sub-type structure is more accurate for the wider range of skin undertones we see in Filipina clients than the 1980s 4-season model, and it is the standard taught in Korean personal color analyst certification programs.

Can my season change over time?

Your underlying skin tone (the structure measured by the instruments) does not change. What can shift over time is the visual appearance of your skin, eyes, and hair, due to sun exposure, hair coloring, hormonal changes, or aging.

How long does the analysis take?

The standard 1:1 PREMIUM Individual session is 1.5 hours in-studio. The Complete Personal Color + Face & Body session is 2.5 hours. Group sessions add 30 to 90 minutes depending on group size. Plan for an extra 30 minutes from arrival to departure.

Can I record or photograph the session?

Photography for personal use is welcome — most clients photograph their draping sequence and palette card to share with friends, family, or stylists later. For filming intended for vlogs, social content, or other published use, please flag this at booking so we can set guidelines on a case-by-case basis depending on the intended use.
