 How to Tint Japanese tissue for Book Repair

I only learned how to tint Japanese tissue for book repair after many years of making do with whatever colors I already had around. When I finally did start color matching myself I couldn't believe how easy it was to at least get really close. Getting an exact match took longer but it is a fun process anyway so I do recommend trying it. And it only requires a few tools and materials.
A small but deep cup
A brush (maybe 1/4 inch or 1/2 inch wide).

Something to paint on that the paint won't stick to like glass, pyrex, plexiglass, or what I have here is an enamel photo processing tray.

Japanese tissue. I am using Sekishu here but many others will work fine too.
A Water Spray Bottle (optional)
The Acrylic Paints that will make the right color for you. That will be different for each situation but here is a list of a few sort of standard colors for paper. I like Golden paints particularly.
Titan Buff
White (whatever kind)
Raw Umber
Burnt Umber
Yellow Oxide

You will only need a small amount of each. A pea sized dollop is a good way to start but with fluid paints two or three drops will work.
Some colors go further than others meaning that it is best to start with tiny amounts until you get a sense for how much the addition will change the overall color.

After mixing the colors with no water added (or just a tiny bit), use the spray bottle to add water a bit add a time. The spray helps it blend in faster but you can just dribble some water in if you don't have a spray bottle handy.

Watch for lumps. It should be watery like milk rather than cream. You will need at least a 1/4 to a 1/2 cup of liquid to make it easy enough to paint with.

When you think you are getting close to the color you need, hold the cup near the object you are trying to match (end-sheet, page or cloth cover) to take a look. Don’t spill!

When you think you have a good match test it out on a bit of the paper you are going to color. Dry it. The color will change so make sure it is really dry. Hold it next to the paper you are trying to match. Notice: Too dark, too light? Needs more red or yellow?
This may take a long time to match the first few times but you will get faster at it. I think my first color match took 2 hours! Now it can be 15 minutes.

There is a color wheel that I have always liked called the Analogous Color Wheel. It is for oil paints but I like the muted colors. It can help you to see what direction to take the color in.

Once you have the color, get a bigger paint brush. I like a two inch Purdy for this. I used an enamel photo processing tray, but you could use anything so that the paint won’t stick to it.

Paint away. Fairly quickly to avoid leaving brush strokes.

Peel it up while it is still wet and then dry it. You still have to check to see if the color is accurate so waiting for it to dry can be annoying.

I will typically use a bit of paper towel to dry it but be careful. Letting wet paper sit on top of any pattern can imprint that pattern into your paper. So keep it moving!

You can use a hair dryer too of course.

Typically I will make a batch of several sheets of slightly different colors to match different books. This saves a lot of time.

Here is the book I was working on.

I matched the Japanese tissue for the hinge color.
