Violas love the cool season and really struggle with the arrival of heat, eventually dying by summertime. Pale color now may be a sign of this problem or could also be due to wet soil conditions that are excluding oxygen from the roots. A very high pH may also be causing some loss of green leaf color if the most affected leaves are the youngest leaves out near the end of a shoot. Maintain moderate soil moisture and iron supplements can alleviate the iron deficiency. Next year prior to planting add a 2" layer of peat moss or compost to the soil.
Thanks for the question. Please stop in again soon!
