Logo
Five lockups, one clearspace rule, one minimum size, and the colours the mark is allowed to sit on.
Every file here is a true vector lifted out of the brand book — traced
from the PDF's own outlines, not redrawn. The masters are filled with
currentColor so they inherit their ink; the download variants have
a key colour baked in.
Five
Lockups
Pick by the shape of the space, not by preference. The primary is the default; the horizontal exists for wide shallow bands; the small-use mark exists because the descriptor stops working below a certain size.
The Thai lockup is not a translation bolted on — it is the same construction with the Thai descriptor, and its clearspace ratio is identical.
Grounds follow the duotone pairing in the sidebar.
The lockups
Guideline p5, p8, p11, p13The T
Stem
The brand book states the rule in Thai: “ระยะโดยรอบตราสัญลักษณ์ = ความกว้างของเสาของตัวอักษร T” — the clear area on all four sides equals the width of the stem of the letter T.
That is a proportion, not a measurement. It scales with the logo, so it can never be expressed as a fixed pixel value.
Measured, so you can compute it
Measured p7, p10Measured off the guideline’s own outlines, that stem is a constant 0.1185× the height of the SOT monogram in every lockup — primary, horizontal, Thai and small-use alike, to within 0.0002:
clearspace = 0.1185 × monogramHeight
= 0.0533 × primaryLockupHeight
= 0.1180 × horizontalLockupHeight
The cyan field is the clearspace. Drag the slider — it tracks the logo exactly, because the rule is a ratio.
100 px
35 mm
Below 100 px on screen or 35 mm in print, the descriptor stops resolving. At that point you do not shrink the primary lockup further — you switch to the small-use mark.
The small-use mark is a different drawing, not the same one scaled: the stepped notch in the S is resolved out so the letterform survives at size.
The threshold
Guideline p11On
Colour
“สามารถวางบนพื้นหลังสีตามที่แนะนำได้เลยโดยไม่ต้องเปลี่ยนสีหรือส่วนประกอบใด” — the logo can be placed on any recommended background colour without changing its colour or any of its components.
Which means the decision is only ever which key colour. There is no special one-colour version, no knocked-out box, no containing shape.
A gradient, a busy photograph, or an off-palette colour is not a recommended background. On imagery, put the logo on a flat halftone-duotone field.
All eight key colours
Guideline p6, p9, p15Do
Not
The first two below are stated outright in the brand book. The rest follow necessarily from “without changing its colour or any of its components” — they are marked as implied rather than quoted, so you can tell the difference.
Six ways to get it wrong
Guideline p6, p9, p11, p48Never stretch“The logo should not be stretched.” (p48) In a key visual only the key visual scales non-uniformly.
Never recolourOff-palette colour. The logo takes a key colour or nothing. (p6, p9)
Never go under the floorBelow 100 px the primary lockup is the wrong asset — use the small-use mark. (p11)
Never rotateImplied. The lockup sits square to the artwork in every example in the book.
Never on a gradientImplied. Grounds are flat key colours, or a duotone halftone field.
THAILAND
Never rebuild from partsImplied. Do not re-typeset the descriptor or re-space the lockup. Use the supplied file.
Assets
Every offered colour is a key colour — there are no off-palette variants, by design. SVG for print and web, transparent PNG for decks and social.
For code, prefer the currentColor masters in assets/:
inline them as SVG or use them as a CSS mask and they inherit their ink from
whatever pairing they sit in. That is how every logo on this site is drawn.
