䒐 (U+4490): one of the meanings given for U+4490 at zi.tools is 急躁, 'short-tempered', which suggests some semantic overlap with this character's definition, 'impatient';

I suspect that ⿰𣊔色 is a printing error for U+4490 䒐. 《粤語詞匯溯源》（香港：商務印書館，2019年） p. 176 gives the word 䒐䒏:



Cf. WS2021-01385 which writes the same word as {⿰忄盟}𢛵.

I suggest to postpone pending additional evidence.

unify to 䒐 (U+4490)

Agree with Lee and Andrew, but there is no need to add any new UCV rule.

BTW, I do not think 䒐䒏 is a proper word form for the Cantonese word mang2zang2, but so many people and scholars use this form.

Withdraw.
