My 1998 has the "medium neutral' leather interior color code (521/522) and I've been trying to find the appropriate paint color to help refinish some of the plastic pieces that are scuffed. My interior door bezels are mismatched so I decided to use them as my experimental pieces. A lot of discussion I've found regarding paint-matching the interior focused on greys so I thought I'd start a thread specifically on my experience trying to find a match for the medium neutral color and potentially hear new options from other members.

As part of the prep all pieces were 1) washed with soap and dried, 2) sprayed with SEM adhesion promoter, 3) hit with a 3-4 light coats of color, and 5) 2-3 coats of SEM Low Luster Clear

Since SEM has a very good reputation I started there. Lesson 1) DO NOT TRUST THE ONLINE PAINT CHIP PDF. When viewing on my computer, the SEM Lt. Neutral (15863) looks like the correct color. IT IS NOT. I don't have any pictures of this, but the paint color is more akin to what you'd see in a GMT800 or maybe an Escalade. I initially picked this color because of the 521 code and how it looked online, but definitely a mistake.

So next I went with the "medium neutral" (15883). When you look at the pictures below you'll probably think I grabbed the wrong color somehow. I know I did after comparing it with the dash fuse cover. At this point, I actually thought something was wrong with can I got from the store and bought A SECOND can on Amazon just to check. Same grayish color with very little brown.

Frustrated, I took a half-day off during the week to drive to the nearest SEM distributor and chat in-person. I brought him the painted sample and fuse cover for comparison, and explained the full process. He looked, did some test sprays and confirmed with a can they had in stock--all very gray and muted brown--and nothing like what I would expect. He then took his paint chip page and compared with one from an older binder. Unfortunately, when compared together it's very easy to see how poorly they match. The old paint chip is slightly glossier and has more brown tone in it than the current color. He explained that I'm not the first person to raise issue with color matching and that the quality has been an issue in the last couple years due to supplier challenges. He even just re-sprayed the interior in his 90s Ford in a black color and stated that 2 out of 6 bottles came out with a different sheen than the other 4. He said that making a custom pint is always an option at about $100 and would take about a week.

At that point I decided to go with the other brand I've commonly seen, Colorbond. There are two 3-digit codes I wanted to try: 158 (Medium Neutral II) and 650 (Neutral Tan) but as of this post have only been able to find/try 650. The color is definitely a lot closer than SEM but sprays on rougher. This is negated once the clear coat is sprayed but I could definitely see/feel a difference. Since I was much more satisfied, I sprayed the instrument cluster bezel and lower dash plate as well to get a bigger comparison. When next to other large, OEM-color pieces it is evident that they're not the same color, but it's not too terrible. I wish I could get my hands on an affordable can of 158 just to see what the difference is, though.

All pictures will be in the following post.

As can be seen, depending on the light, the differences in color range between stark and hard to distinguish. I think an additional challenge is also the variance in color among OEM parts and Aftermarket. For example, the power-window switch panels are OEM, but are distinctly different color from the rest of the door panel. Similarly, the interior door handles are all Dorman units and are close matches for the Colorbond bezel. When the SEM bezel is up though, the color difference is very very evident. In the corner of some pictures you can also see the A-pillar trim color which looks different from both the OEM dash color and the Colorbond instrument panel trim pieces.

At this point, unless I can get a can of Colorbond 158 to test, my options are to either stick with the Colorbond, or go the custom color route. As stated earlier my intention of this thread is to a) have a discussion and actual images about the 'neutral tan' interior color, and gather up reliable information and solutions from other members with the same interior color.

A pint in a week?
My local SEM supplier can mix up a perfect match, in any color I desire, in pints, quarts or even gallons along with aerosols.
...in a a couple of hours or three, depending on how busy they are.
They match via a spectrophotometer
The same machine that they use to color match paint for body work.

I put all 7 of the interior plastics in my '98 that it never came with, but which the early ones did. They came out of 3 different trucks in three different colors.
The custom mix for those panels matches the dash & the door panels perfectly.

Yeah I was a bit surprised, but it was a Wednesday and I didn't really follow-up for clarification if a week really meant 7 days or "next week" like Monday. To be fair to the guy, it looked like he was the only one in the shop and was handling everything in the front and back so I tried not to monopolize his time v. the other customers.

I'll probably have to go that way in the future though. This little experiment has already run about $90 in paint cans trying to get the right color with futility.

Hello, paint and ink are similar when trying to match a previous color. I’m not a body guy or a painter, but same principle, I’ve been a printer for 39 plus years. I’ve mixed my own inks to match a previous printed job so it will look the exact same as the year before or 10 yrs before. Different companies use different inks or pms colors to blend and I can say the same color from one company to next is different even though they are supposed to be the same. Heck I’ve gotten batches of ink from same company that will be off 10-20 points, as we use densitometers to measure the density of the inks. Sometimes we just redo whole job to make sure it looks same throughout! It’s a headache to keep consistency. But end result will be better. btw I’m getting ready to paint my interior plastic as well, ugh!!

When I order materials for interior projects, I always order 10%-20% more than required. Greater the amount, the less the percentage
The 'oops' factor. I have horror stories of near completed custom one-off jobs that have suffered seriously phukd-up damage in the shop, requiring un-paid-for hours to fix + the replacement of stupidly expensive yardage at my cost.
...and of course the owner's coming to pick it up tomorrow. Or in an hour. Either way, deadline missed.
Had a customer show up the day after the job was done. Finished & out the door. Paid for.
Tinkering on the car & he jumped into it with a screwdriver in his back pocket.
The night he got it back home.
The seat wasn't 12 hours new.
Nope. He ain't makin' the show tomorrow.

If I hadn't ordered that extra at the start, replacement materials ordered may or may not be an exact match to the originally spec'd.
It might look the same on the bench, but once that new is stitched next to the existing, all of a sudden there's a slight but obvious difference in color between the two. A sore thumb.
The odds of that replacement material coming off of the same roll the original order as cut from?
Yea. Sure. A definite maybe.
From the same batch? Better, but not by much.
Man-made textiles are of little worry & are much more consistent than wool, cotton or leather.
But any material I order has the possibility of being 'off'.
The natural materials can vary in color, even in just the slightest tone or tint, from one order to the next.
A different batch number. Made on the same day.
The same dyes & amounts, but made at a different mill.
Same mill, different day, different shift.
Even the humidity on the day of production can be a factor.
A lot of variables.

Leather @ $15.00/sq.ft. works out to $250 per linear yard. (36"x 54")
A 2.5 yard repair? That kinda stuff raises the blood pressure. Hyperventilation. Sore teeth.

When a project is finished, with no oopsies, the customer gets the extra.
Just in case. Could be for the next day or 10 years down the road.
No color-match issues.
No minimum order required amount, which is usually 3x more than what the repair needs.
Hopefully, it'll match.
...and the shop doesn't get over-stuffed with odds & ends.

Why not just spray everything?
