Color text & highlight text

It is possible to use html and css to color/highlight text:

<span style="background-color: #43e">Background</span>
<span style="color: #00ff00">Text</span>
<span style="background-color: #4433ee"><span style="color: #0f0">Both</span></span>

I wish there faster way to write it, maybe something like this (or similar to this)
<#43e>Text</#43e>
<<#00ff00>>Background<</#00ff00>>
<<#0f0>><#4433ee>Both</#4433ee><</#0f0>>

I don’t know if such feature should be native or not, if not then please move it to plugin requests.
