インテリアデザインアドバイザーとしてClaudeを使う方法：Stella Skillガイド

It can decide a room for you, which is a different and more useful thing. It will name the style direction, give you specific paint colours with the undertone explained, size the furniture against your room's real dimensions, fix the lighting and tell you what to do first. What it will not do is produce a picture of the finished room. If you want a render, this is the wrong tool. If you want to know what to buy and what to paint, a render was never going to answer that anyway.

No. The Stella skill is written design advice only, and it says so rather than implying otherwise. Everything it produces is text you can act on: colour names, measurements, layouts, fixture types and reasoning. Room visualisers are a separate category of tool, and they tend to produce something that looks good and cannot be bought.

The most common cause is lighting. A room lit by one bulb in the middle of the ceiling gets flat light from a single point and dark corners, which reads as unwelcoming no matter what furniture is in it. The standard fix is three layers: ambient for the general level, task light where you read or cook, and accent light at the edges to give the room depth. Two lamps and a dimmable bulb change a room more than a new sofa. Other frequent causes are everything matching, nothing at eye level, and a rug that is too small.

Yes, and the named colour is the part worth having. Stella works with Farrow and Ball, Little Greene, Dulux and Benjamin Moore ranges, and explains the undertone and how it shifts between a north-facing and a south-facing room. What no AI can do is tell you how the colour will look in your light, so buy the sample pot, paint a large square, and look at it in the morning and at night before committing.

Yes, and it is one of the things the skill asks about before advising. Rental constraints change the answer rather than ruling it out: layout, lighting, rugs, textiles, freestanding storage and artwork placement all do a lot of work without touching the walls. Say you rent at the start and the recommendations come back in that shape.

Room dimensions, which way the windows face, ceiling height, what is already in the room, anything that cannot move such as radiators and alcoves, your budget, and what you dislike in your own words. Vague inputs produce vague advice; the specific answers come from specific constraints. Ask it to separate what you can do this weekend from what needs money or a tradesperson.

For one question, barely. Across a house, clearly. A room is never a single question: you ask about the living room, then the hallway it opens onto, then whether the kitchen can take the same green. A loaded skill keeps the decisions already made, so colour flow between adjoining rooms is handled rather than each space being treated as if it stood alone.
