Start with the documented color character
Tricorn Black is described by Sherwin-Williams as a true black without an undertone. Temperature is a useful description, but neighboring materials can change the impression. Tricorn Black is an appropriate baseline for comparing blacks because the manufacturer explicitly describes it without undertones.
Why the white plaster and oak doors relationship matters
Repeated black casings can divide a room into many outlines; the total number of painted edges is a design decision beyond color selection.
Tricorn Black and Black Magic both have a published LRV of 3. That equality describes reflectance, not matching colorants or identical undertones. Black Magic is a very dark black with a slight warm influence. This supplies a named color control; the LRV gap alone does not identify the warmer, greener or pinker paint.
Use Black Magic as a control
Temperature is easier to assess when Tricorn Black has enough light to show its hue. Check a lit panel beside the actual metal or wood, then inspect the shaded section. A very dark surface may function mainly as an outline even when its published color description has a distinct temperature.
Separate a persistent cast from a comparison effect
Map every black edge in the room before painting; the number of outlines matters as much as the shade.
Judge the temperature description against the full white plaster and oak doors arrangement. A warm or cool label is a useful starting category; it cannot guarantee that Tricorn Black agrees with every material assigned the same label. The wood-floor pairing guide covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
