布 Bù is the clearest place to start if you want a one-character Chinese surname connected to Brown. It is the first character of 布朗, Bùlǎng, and it is independently documented as a surname. 步 Bù offers the same Mandarin sound with different writing; 卜 Bǔ keeps a nearby sound but changes the tone. A colour-based choice is possible to research, but it needs more care than translating “brown” and using the result as a surname.
First decide what the Chinese form needs to do. 布朗 keeps more of the original surname recognisable. A short Chinese surname gives you a different kind of personal name, usually followed by a given name. Neither choice requires you to replace your existing family identity or an established Chinese surname.
Why 布朗 is a starting point, not a complete recipe
English Brown has the /braʊn/ sound, with one syllable. 布朗 divides its approximation into two Mandarin syllables. The first, bù, does not preserve English /br/ or its vowel; the second contributes the lǎng sound. Reducing it to 布 is therefore a deliberate shortening of the transliteration. English sound, 布朗 transliteration.
That gives you an honest introduction: “I took 布 from the Chinese rendering of Brown.” It does not mean that 布 translates the colour. If recognisability is your main concern, keep 布朗 and avoid forcing it into a one-character pattern just because that pattern feels more Chinese.
布 Bù: retain the actual opening character
The dictionary lists 布 as a surname as well as recording its familiar cloth-related meaning. This is stronger evidence than simply noticing it in foreign names. The surname can stand independently. Its ordinary meaning does not prove that a particular 布 family were weavers, and it does not turn Brown into a textile surname. 布 dictionary entry.
Choose 布 if you want the most transparent written connection to 布朗. Its fourth tone gives a firm, falling opening. You may need to clarify that 布 is your chosen surname rather than the beginning of the longer transliteration. “布朗的布” is a practical spelling explanation when speaking with someone who knows the foreign surname.
The given name still matters. 布安, Bù Ān, sounds like 不安, “uneasy.” The appealing meaning of 安 does not erase that whole-name association. This example is a warning to test the complete sound, not a reason to reject 布 in every pairing.
步 Bù: the same syllable, a new association
步 is also a recorded surname. Its everyday meanings concern walking, steps and stages. It is exactly the same Mandarin syllable and tone as 布, so this option preserves the first sound of Bùlǎng while changing its character. It is a substitution, not the original first character. 步 dictionary entry.
For a self-chosen name, you might enjoy a personal association with moving forward at your own pace. That interpretation belongs to your choice; it is not Brown's etymology or the history of every 步 family. Select 步 if that new association matters more to you than retaining the visible link to 布朗.
Because 布 and 步 sound identical, changing between them will not fix a spoken homophone with the given name. A pleasing written story cannot by itself solve the 布安/不安 example: 步安 has the same sound.
卜 Bǔ: a tone change worth hearing
卜 is documented as a surname read Bǔ, with a third tone. It is not the neutral-tone bo heard in 萝卜. Compared with 布, the tone changes while the basic syllable remains close. 卜 dictionary entry.
The character has meanings connected with divination and choosing a place. Those senses are not evidence that choosing this surname predicts your future, or that Brown has a divinatory origin. Consider it for the sound and the character you actually prefer, rather than an invented promise about destiny.
Tone changes need to be heard in context. 卜安 Bǔ Ān is not an exact tonal match for 不安 Bù Ān, but a learner or someone reading unmarked “Bu An” may still make the association. This remains a listening example, not a finished name recommendation.
What about translating the colour?
Brown often developed as a descriptive name referring to hair or complexion. Other histories include personal-name origins, translations and adaptations from different languages. This does not establish a particular ancestor's appearance, and it does not require the person choosing a Chinese name to represent a skin colour. Brown surname history.
褐 is worth discussing rather than dismissing. It has a brown-colour meaning, and the dictionary's Guoyu section records surname use. However, that section gives hé, while the page's modern headword gives hè. The colour connection is therefore real, but a single default surname pronunciation would conceal a dictionary distinction. 褐 dictionary entry.
I would treat 褐 as a conditional, meaning-led option: settle the pronunciation for your intended Mandarin community and test how easily people recognise it as a surname. It loses the audible link to Brown and asks for more explanation. Its historical clothing meanings also do not justify assigning you the surname of a scholar associated with plain dress; that would add an unsupported cultural bridge.
Choose what you want to preserve
Use 布 as your first comparison if the written link to 布朗 is important. Try 步 if you want the same opening sound with a different personal association, or 卜 if you prefer its character and are comfortable making the tone clear. Keep 褐 under consideration only if colour meaning matters enough to resolve its pronunciation and everyday recognition.
Then add the given name and test an ordinary introduction. Ask the listener to repeat it before showing the characters. The strongest choice is one you can pronounce, explain and enjoy using as a complete name—not merely the shortest translation you can find.
