Yes and no. Harlequin is a Macrophylla that turns blue with white margins in acidic soil. Vanilla Strawberry is a paniculata and paniculata blooms generally tend to start white or some off-white color. VS blooms start creamy whiteish regardless of the soil acidity. As time passes, the color fades to light pink and then a strawberry reddish color. It will not turn blue. Go to hydrangeasplus.com to view many candidates. Observe that Macs with "red" references in their name will grow purple in acidic soils so keep that in mind. Whites will always bloom white but, will turn other colors as the blooms fade. Finally, Invincibelle is another option; it is an Arborescens version of Annabelle that is always pink regardless of soil acidity.

Most hydrangeas will do well with indirect light if the shade is bright indirect light during the growing season. If unsure, you can test the waters by planting one under those conditions and seeing what happens. You can also look around your neighbors yars and see what seems to grow under similar conditions.

It depends on your soil pH (a lot of the New England area has rather acidic soil) and on the specific hydrangea cultivar. Some pink flowering forms of H. macrophylla tend to be very resistant to pH and hold their color well but most do not. And even those that are resistant to pH will not maintain the same clear color they had in a more neutral soil but become a bit of muddy mauve or pinky-purple in very acidic soil.

Since your Nikko bloomed a bright blue, that pretty much confirms the soil acidity. You can decrease the acidity by applying lime to the bed. White flowered macs will always bloom white and all paniculatas bloom white (or greenish-white) but will age to various pink tones. Or you can try the new 'Invincibelle Spirit' that Luis mentions.

Can ask where you found the 'Raspberry Parfait'?

I saw it advertised in a Michigan Nursery back in December but, now I cannot remember which one it was.

Might it have been Michigan Bulb? To my knowledge, this is the only "nursery" that sells this variety, which is NOT a registered cultivar of hydrangea. IOW, they made up the name and assigned it to another variety of hydrangea (I suspect to avoid patenting regulations). You should also know that Michigan Bulb has one of the worst reputations of any mail order plant source - inaccurate or made up plant names, puny, half-dead plants and appalling customer service. Look at the vendor review forum here on GW or check Garden Watchdog.

Look for Hydrangea macrophylla 'Buttons and Bows' - that is the closest legitimate hydrangea cultivar with the pink bicoloring. And it holds its pink color very well.
