Still seems like I'm getting the same issue.

sealed trait AppColor {
    val asHexString: String
    val asScalaCssColor = Color(asHexString)
  }
  object AppColor {
    implicit def equality: UnivEq[AppColor] = UnivEq.derive
  }
  case object FacebookBlue extends AppColor {
    val asHexString = "#3B5998"
  }
  case object Cinnabar extends AppColor {
    val asHexString = "#DD4B39"
  }
  case object DeepSkyBlue extends AppColor {
    val asHexString = "#1dcaff"
  }

  private val domain = Domain.ofValues(FacebookBlue, Cinnabar, DeepSkyBlue)

  val bgColor = styleF(domain)(c => styleS(
    backgroundColor := c.asScalaCssColor
  ))

Explicitly stating the type of the domain fixed the issue. Going to close the thread. Thanks for the help :)

private val domain = Domain.ofValues[AppColor](FacebookBlue, Cinnabar, DeepSkyBlue)

Oh of course, that makes sense knowing how Scala LUBs. That would've been frustrating but I'm glad you figured it out.
