One of my favourite styles, that looks like it could be a good Saison. I usually use some special B or the likes for a colour addition that also brings some flavour rather than something like midnight wheat. Colour can officially be 5-14 srm so colour additions are pretty unnecessary, but it will be fine the way you are going as well. Many people do use sugar in this style, I don't and would say its only optional, I usually brew mine up around 1.06-1.065 and they dry out plenty without the sugar.
Saisons can actually be pretty simple or pretty complex on the grain bill and still come out to style, as long as you don't use the wrong grain like an american crystal or something sweet like that. In any case, I have made a few, I usually mash around 64-65 and they come out nice and dry, however I prefer the WLP566, it doesn't stall out and will attenuate pretty much anything down sub 1.01. I haven't used the french version (590) but I know a brewer who does use it and I believe it is similar in not stalling and high attenuation so I am sure it will be fine too. wlp565 on the other hand really likes to stall out.
Only other advice I have is let it ferment nice and warm, not above 30c but if you ferment down around 20 you won't get as much of the 'saisonyness'

23 should be ok. I don't have a ferm chamber and let them go as high as they want, sometimes up to 26-27C the first couple days, never had an off flavour and actually got a silver in a bjcp comp for the first one I ever brewed...
Good luck with it, I am sure it will turn out awesome! Oh and they also get much better with some age. Totally different beer after a month or more of conditioning, compared to a week or 2.
