However Hume in this passage,
Book III-Part I-Section 1 of his A Treatise of Human Nature;
in [= mine]
imply there are facts of morality, i.e. moral facts and thus Morality is Objective in that perspective.
See: 'There are Moral Facts' here;Vice and virtue [morality], therefore, may be compar’d to sounds, colours, heat and cold, which, according to modern philosophy, are not qualities in objects, but perceptions in the mind:
And this discovery in morals, like that other in physics, is to be regarded as a considerable advancement of the speculative sciences; tho’, like that too, it has little or no influence on practice.
The "What-is" of Color, Sound, Heat & Cold are Facts?

The point is those who relied on Hume's NOFI [no ought from is] and jumped to the conclusion 'Morality is Not Objective' are seriously mistaken.

This ["is-ought"] passage is often misread because it is taken out of context and because it is immediately preceded by the observation that moral distinctions are not a product of matter of fact knowledge. pg 93
