Color specified as

... try <font fgcolor="#ff00ff00">green</font> The rule is: <font fgcolor="#aarrggbb">color</font>. The meaning of the Alpha component is well explained in @MarcinOrlowski's answer. — Phantômaxx

On Android color is defined as ARGB where A stands for alpha channel (transparency). For alpha, value of 00 means fully transparent, and FF means fully opaque. So when you define your color as RGB, ommiting A part, then A is being considered as set to 00 which in result makes your color fully transparent, thus your color is invisible and may look like not working. This behaviour sometimes can differ and lack of of A can be interpreted as opaque, but this is rather exception so it's safer to always specify alpha value. BTW: color cannot work anyway :)
