How Do I Keep Hydrangeas White?

My mom and I bought a beautiful white hydrangea in April. We planted it with compost soil mixed with regular topsoil. The blooms have turned green, and the leaves are curling. The temperature here in San Diego has remained cool (about 70 to 75 degrees). The plant gets at least 4 to 5 hours of sunlight. How do we keep the blooms white? The hydrangea is a big leaf with a large cluster bloom, sorry I don’t have it’s exact name.
