For the uplight, you could go a few routes, especially with respect to dimming functionality. And some fixtures don't support dimming, so you need to figure that out. To that end, I suggest you think through the use cases. For example, the use case that I think I'd appreciate most is late evening, after you've retired to another room of the house, at which time a mellow indirect glow from the skylight cutout would be particularly pleasant. You might also want the more light from this source on occasion, in which case you'd want brighter lights on a dimmer. That being said, here's some options. I'm thinking two, centered on the skylights, mounted near the bottom rim of the cutout (just above the beam probably). Regarding the pendant, I know that selecting pendants is hard enough without more to think about, but one downside of a single pendant vs multiple pendants is thhat single sources create worse shadows. And the clear glass pendants above exacerbate this harsh shadow problem by being point sources, whereas the Fillsta, for example, mitigates this problem because it's effectively a uniform 31" sphere of light. This large diffuser also makes it possible to use a brighter source. For example, you could put a 300W equivalent CFL in the Fillsta, but such a bright light would be unacceptably harsh in a point source like the clear glass pendants above.

It was from Troy Lighting several years ago (Eclipse series, they had them with various numbers of lights) and I don’t think it’s made anymore: https://www.lightingnewyork.com/product/troy-lighting-eclipse-pendant-f2805.html Maybe someone knows of something similar, good luck.

@Mrs Pete, I'm curious... If I was to do an all white kitchen, wouldn't it still hold true that all the color is at the bottom (the flooring).? How would you balance it out in that case, or would it even need balancing? I decided to go with a two toned kitchen because my kitchen gets very little sunlight (many many mature trees in the neighborhood). With my dark flooring and 90's orange oak, I'm in a sea of wood. I picked white uppers to brighten the room and the stained bottom cabinets for their durability and easier maintenance. (My cabinets are already ordered so I'm not sure I could make that change this late but I'd still like to learn.)
