Honestly, if you paint your house burnt-orange, you're home is going to be the laughingstock of the neighborhood - and good luck ever trying to resell it in that color...
...plus, the dark color will absorb the heat making your home even more expensive to cool.

Spend your money & energy where it makes the most sense: Your landscaping.
Large trees will help shelter your house from the sun, and there are plenty of bright, flowering, yet drought and heat tolerant landscaping plants and spreading ground covers which will do so much to improve and brighten up your curb appeal, because dead grass is not inviting.

Finally, that concrete driveway & front walk is an ugly heat sink - replace them with masonry pavers which will allow you to plant groundcover in the gaps and help green up your home.
