“Anthropic's colors and fonts in one tidy card. Solid hex codes, but it describes a tool that doesn't ship”

Post on X

What it does

Gives the agent Anthropic's brand palette (four neutrals, three accents) and fonts (Poppins for headings, Lora for body, with fallbacks). It also describes styling features as if a script applied them, but no script or steps are included.

When the agent uses it
When an artifact should look like Anthropic's: brand colors, style guidelines, visual formatting or company design standards apply.
Who it is for
Install if you make slides or documents that should look like Anthropic's. Skip if you want another brand or a working PPTX styling tool.
What it costs
49 lines, about 604 tokens once the agent loads it.
The description the agent sees

Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.

What it tells the agent to do

  1. Use the dark #141413 and light #faf9f5 for text and backgrounds, with grays for secondary and subtle elements
  2. Set headings of 24pt and up in Poppins, falling back to Arial
  3. Set body text in Lora, falling back to Georgia
  4. Pick text color based on the background
  5. Fill non-text shapes with accents, cycling orange, blue, green
  6. Apply colors as RGB values via python-pptx's RGBColor class

Lines worth reading

Straight from the file, with why each one matters.

  1. line 3Use it when brand colors or style guidelines, visual formatting, or company design standards apply.

    The trigger is broad. "Company design standards" could match any company's brand, not just Anthropic's.

  2. line 66No font installation required - works with existing system fonts

    One line later it says to pre-install the fonts for best results, and line 36 says the same. The skill can't decide.

  3. line 57Cycles through orange, blue, and green accents

    The one real rule in the Features section, and it is a good one: a set order the agent can actually follow.

  4. line 51Smart color selection based on background

    Smart" with no rule behind it. The agent has to guess what the smart choice is.

  5. line 72Applied via python-pptx's RGBColor class

    This shows the text came from a PowerPoint script that isn't here, even though the description promises "any sort of artifact".

Watch out for

Nothing risky that Kin could see in SKILL.md. Scripts beside it were not read.

The scorecard

  • TriggerSays when to use it
    6/10

    Says what and when, but generic terms like 'design standards' can misfire on other brands

  • FocusOne clear job
    8/10

    One job: Anthropic's look. Clear from the name alone

  • LeanLight to load
    8/10

    About 600 tokens, but the font rules are repeated three times

  • ConcreteSteps you can follow
    5/10

    Exact hex codes and fonts, but no steps, no code and no check that it worked

  • SafeSafe to run
    10/10

    No commands, no network, no secrets. Just a palette

What it does well

  • Every color comes with an exact hex code and a stated role, so the agent never has to guess at 'Anthropic orange'
  • Each font has a named fallback (Arial, Georgia), so the output degrades gracefully
  • Short enough to load at almost no cost

How it could be better

  1. Replace the feature list with steps

    The 'Features' and 'Technical Details' sections describe automation that doesn't exist, so the agent reads claims instead of instructions.

    Add
    ## How to apply
    1. Text and backgrounds: dark text `#141413` on light `#faf9f5`, or light text on dark.
    2. Headings 24pt and up: Poppins; if not installed, Arial.
    3. Body text: Lora; if not installed, Georgia.
    4. Non-text shapes: fill with accents in order orange `#d97757`, blue `#6a9bcc`, green `#788c5d`, then repeat.
    5. Check: no colors outside this palette, and every heading and body run has a font set.
  2. Name Anthropic and the outputs in the description

    'Company design standards' can trigger on any brand request; naming Anthropic and the file types keeps the skill on target.

    Add
    description: Applies Anthropic's brand colors (hex palette) and fonts (Poppins, Lora) to slides, documents, charts and web pages. Use when the user asks for Anthropic branding, Anthropic colors, on-brand Anthropic styling or the Anthropic look-and-feel.
  3. Show the python-pptx code it mentions

    Line 72 names RGBColor but gives no code, so the agent has to rebuild it each time.

    Add
    ```python
    from pptx.dml.color import RGBColor
    DARK = RGBColor(0x14, 0x14, 0x13)
    ORANGE = RGBColor(0xD9, 0x77, 0x57)
    shape.fill.solid()
    shape.fill.fore_color.rgb = ORANGE
    run.font.name = "Poppins"  # headings 24pt+
    run.font.color.rgb = DARK
    ```
  4. Settle the font installation rule

    Lines 36, 66 and 67 contradict each other on whether the fonts need installing.

    Add
    Fonts: use Poppins and Lora if they are installed; otherwise use Arial and Georgia. Do not install fonts unless <the user asks>.
