what color besides black and white are, measurably, most easy to see?

a practical example is when deciding what colour to pick for 'section titles' of long bullet-point text (has sub-bullet points also) on onenote, g-docs, and most anywhere

so im hoping for a software existing or one day that auto-picks a good colour based the colors already on the page such as when there are blue links all over the screen


one post seems to have info on how to measure contrast so hopefully a software person/team would one day make this basic tool, i've wanted it for years and years and decades already

many (80%+) don't even care about UX or anything related to good design, they just don't care or noticed. but for those that do, now one of the common solutions that 'most' ppl do is they 'bold' headings, but 'most' ppl are know essentially nothing on UX, and im sure that almost anyone that is experienced & specialied in this area of clear visuals and presentation of info understand this

we can evidence this as well, in this post about best blackground colour for black/white text, there are info that can be helpful to lead into what would be good contrast.

even without evidence, it's obvious that a darker black (bold) nearby to other blacks (text) is very very hard to see, and does not distinctly stand out (with rare exceptions such as there was one =)


now i luv ux, all forms of design is a favourite of mines, and it's sad that i haven't ever asked any questions on this site, and only have read stuff

i really want to know the answer because i've been wanting to know this for .. for forever. and because it has such a practical and signficant use. take this onenote page, i've text and links everywhere and i can't see clearly what's the most important thing on the page, because sometimes there many important things

but there's just no good markers or signalers that very very clearly separates all the many sections -- there's just too too MUCH info everywhere on the entire screen, and all the info matters enough to keep in my notes

and i can't see what im looking for


colour is so SO useful, and it's unbelievable, that when colour is used in ALL media (for ALL kinds of reasons such as emotions, etc.), we still as a society are not using colour in 'section headings' or just anything related to text in all these web pages on the Web, and we're in 2017.... already

it's really sad

colour is even used for they key goal of clarity in the actually good games, as one of many examples

it's all about clarity

even outside of ux, but design applies to all things, to make everything better


any clarification, please ask
