could be a number of things
mismatched color, can very well be a preset expecting a texture to have additional content, but the content does not exist, and so the texture is trying to load something that does not exist and glitches out. a good example for this, is a mesh that is missing a texture, will default to an ugly purple colour. this can also happen on textures that are missing additional content (basically, imagine a preset that is expecting the texture to have a tattoo for example, but you dont have said tattoo, the texture will most likely change to a different colour also known as mismatched colour, or more commonly known as black face bug/ brown face bug, or in some cases grey face bug, an infamous issue)
so chances are you might not have all the required mods (its clear you have Looksmenu as indicated by the fact you can select presets, but you might not have the other mod mentioned), i would imagine that half of them presets if not all, require Looksmenu Customization Compendium #(due to its shear amount of customization one can apply to their character)
2. 1 of the most common causes of these miscolour bugs, is invalid facegen data or lack of, however since this is a preset i cant imagine that being case, since it mainly applies to custom npc.
3. and finally have you changed your load order at any time, in the same play through (basically have you installed, uninstalled or moved any mod in the load order, either manually or via LOOT) at any time that your character has been created ?
if you happen to have LooksMenu Customization Compendium along with any other mod that edits the character, ensure that LooksMenu Customization Compedium is placed below all of these mods (else they can also cause the issue you are experiencing, as they will override the mod in question and if the preset requires the mod, it will fail, and thus cause this color mismatch bug). also if this mod is moved in an active playthough or any mod that edits the character, then that will cause the color mismatch bug.
Note: what i mean by mods editing the character, i mean any mod that does the same type of thing that looksmenu customization compendium does, for example, other mods that add eyes, hair, tattoos, eye brows etc etc.
lastly, does this bug happen on the actual time to create the character (the very beginning of a new game) or just when attempting to edit them post new game (basically anytime after leaving the vault) ?
