Hey musers,
The post we have to day has been put together by Madeea. It is in fact part of the older Full Breast manual before we went to the web version for ease of updating information. While the pictures are all based on the Full Breasts the instructions and advice are useful for matching any prim breasts or any attachment really. I have included the intructions in the images in text below it for easier translation via web tools for those who do not speak English natively.
Skin matching for your breasts: This can be a tedious process with any prim breast for new and veteran prim breast users. (skin tone shown as it comes out of the box not yet altered) With patience you will be able to get very close but it will not be a perfect match. There are many factors forever changing the way light is reflected on our avatar versus how it reflects on primitive objects. (like the breasts) What one person sees differs greatly from what another person sees based on many parameters. (such as graphics settings) There will not be a perfect graduation between your prim breast and your avatar. These are some of the minor things we endure to be able to have larger full breasts that do not look like square blocks sticking out from our chests. (for more help on managing that line see Skye’s post on smoothing the transition.)
The key is to try to match the shadows from your avatar with the shadows of the prim breasts.
It is best to start by choosing a skin base with shading similar to that of your avatars. Your avatar will have darker tones along the sides of the chest and the under arm area. Some avatar skins have warmer undertones, so you would probably prefer to choose a skin that has base shading from the red color ranges. Avatars with skin tones that fall into the cooler color categories will benefit more from choosing a skin tone with more olive or blue base shading. (in this example the skin is from Al Vulo – Sally natural 2 porcelain) I chose to go with an “Olive” base since the “Skin Set 1 Hud – Reds” have shadows that are still a bit too warm for this skin tone. Find a skin base that works for you and try using the color editor box to tint the base closer to your avatar skintone. I used 10(0) as my base. RGB 225,191,183. You can also manually enter your RGB value via chat with the microphone.
Skin Blend Layers: To help further blend your breasts to your skin, Skin Blend layers can be worn. These are lays of clothing worn to help further blend away markings on your avatar skin. (tattoo layers can also be created: skin blend flies are included) The Skin Blend Layer will appear white until you edit the layer and follow the same process used to tint your breasts. *skin blends are optional and not required for matching all skins. 
In a different Light: Once you have matched your breasts with your avatar skin, you will want to try it in your favorite windlight setting to see if adjustments are still needed. As you can see minor adjustment is necessary. Keeping the same skin base I adjusted my hue value bar to lighten the skin tone. (Soft Nipple options provide a softer edge around the nipple helping them blend smoother against the skin.)
More light comparison: Lighting will always be something we are struggling with and it will continue to change as SL is developed. It poses quite a challenge to prim breasts wearers but with time and patience you can achieve beautiful results. Windlight settings shown are CalWL WL setting, SL midday, SL Sunrise, SL Sunset. *photos are not edited
Lighting and Shadows: Windlight settings shown are LunaJubilee Shadows, CalWL, SL Midday with shadows. *photos are not edited
I hope this has been helpful in understanding better how SL handles lighting and why skin matching can be so complicated at times (this is also true for mesh attachments but SL handles light reflection off a mesh object in a way that is much more like how it handles light reflection of the base avatar mesh so the differences are much less noticeable.)
If you have looked through all of this and are still having troubles you may want to consider this personal skin matching.
If you have a furry avatar and are looking for a white fur texture to work from for milkmade breasts IM cali Ciaco for a free applier.
