COLOR & TYPE SYSTEM — finance channel

FIRST, A CONSTRAINT MOST FINANCE BRANDS IGNORE
Navy-and-gold is the default for this category, which means it reads as
generic in a thumbnail grid where you're competing on 3% of a screen.
Below keeps the trust signal and buys differentiation.

COLOR
  --ink        #10151F   near-black backgrounds, thumbnails
  --paper      #F7F5F1   warm off-white — reads editorial, not corporate
  --signal     #E4572E   the accent. Used ONLY for the one number that
                         matters per frame.
  --gain       #2D9E6F   up
  --loss       #C94434   down
  --muted      #6B7280   labels, axes, secondary text

  The discipline: --signal appears once per thumbnail and once per
  chart. The moment it's on two things it stops meaning anything, and
  the palette collapses into decoration.

  Gain/loss are deliberately not pure red/green — those fail for the
  ~8% of male viewers with red-green deficiency, which in a finance
  audience is a meaningful slice. Check every chart in greyscale;
  if up and down stop being distinguishable, add a shape or a label.

TYPE — three faces, each with one job
  DISPLAY   Söhne Breit / Archivo Black
            Thumbnails and title cards only. Weight is the hook.
  BODY      Söhne / Inter
            Lower thirds, captions.
  NUMERALS  IBM Plex Mono, tabular figures
            Every figure on screen. Tabular is non-negotiable —
            proportional digits make columns jitter between frames and
            it looks amateur the instant a number ticks.

SCALE — thumbnail-first, because that's where the decision happens
  Thumbnail hook   180–240pt, 3–5 words max
  Title card        72pt
  Lower third       32pt
  Caption           24pt minimum ← anything smaller is unreadable on a
                                   phone, which is most of your audience

APPLIED
  Thumbnail    --ink background · one --signal number · 3 words --paper
  Chart        --paper background · --muted axes · --signal on the one
               series being discussed
  Lower third  --ink 80% opacity bar · --paper text

WHAT TO NEVER DO
Gradients on text. Drop shadows on numbers. More than three colors in
one frame. Any of these and it reads as a template.
