ᐅ Experiences with color differences after additions to an old Kallax unit?

Hello everyone,

I am planning to expand my old Kallax shelving unit from the first production year by adding a few more Kallax elements and shelves. It is important to me that the color tones of the existing pieces and the new parts match as closely as possible.

My main question to the community is: What experiences have you had with color differences when adding to older Kallax units? Specifically:
- How much do the colors of old and new parts differ, especially in the white and black versions?
- Are there visible differences caused by refinishing, coatings, or material changes over the years?
- How have you compensated for or concealed any color differences?

I would really appreciate any input, tips, and possibly information about storage times or manufacturing changes at IKEA. I am specifically interested in older models, not the current Kallax, as these seem to show color variations more frequently based on my experience.

Thanks in advance for your feedback!

I have an older Kallax in the white version, and when I bought additional units two years ago, the white shades were definitely different. The new pieces appear noticeably cooler, while the older one is more of a warm white. I then touched it up with a matching paint – this reduced the difference.

Hello Nepetrit45,

First, I want to commend you on your very precise question – it makes providing a focused answer much easier.

Regarding color differences in old versus new Kallax shelves: IKEA has indeed made several visual changes over the years. This applies to both the melamine resins used and the surface coatings. These changes are rarely officially documented, but within trade circles and collector forums, the first generation is often described as having a warmer color tone.

In older versions, I observe a slight yellowing in the white parts, also due to UV exposure. Newly purchased additions from the current range are usually brighter and have a slightly bluer white tone. The black lacquer tends to be somewhat more matte and can show slight gray undertones, depending on the production batch.

To balance out color differences:

1. Pre-treating with fine sandpaper reduces gloss variations.
2. Using furniture markers or spray paints that exactly match the original color (important: test first in an inconspicuous spot).
3. If a professional solution is desired, it is advisable to completely repaint all visible parts to achieve a uniform color tone.

An important question: What condition are the old parts in? Are they already showing signs of wear or slight discoloration? If so, the color mismatch will be even more noticeable.

I hope this helps you. If you like, feel free to describe the current condition of your existing Kallax elements, and I can provide more specific advice.

I can only confirm that! My old Kallax has this pleasant, almost nostalgically warm patina, which feels really cozy. The newly purchased parts seemed completely "foreign" at first glance in comparison.

UV light exposure and yellowing

Exactly, I’ve heard it’s also because different plastics were used back then, which reacted more strongly to UV light. Unfortunately, this results in slight yellowing that you hardly see anymore now.

For me, the best trick was to stick a thin cover film (a matte protective film) on the inside of the shelves – this hides minor color differences and protects against further discoloration. If you’re interested in a little DIY tip: a wood veneer in a neutral gray tone can improve the overall look. 🙂

That makes your shelf a real eye-catcher, even if small color differences remain. Fingers crossed you find a solution you like!
