Bring Color & Harmony

Into Your Space

Professional color consultations to save you time, money, and bring your interior color vision to life.

Avoid expensive color mistakes

Painting your home is an investment, and one wrong color mistake can be costly. Most people don’t realize that every color decision made impacts and influences the next. From choosing the right white, neutral, earthy tone, or bright color, I guide you in the correct direction to save both time and money. Let me help you get it right the first time.

A personalized color palette for your space

Your home is unique to you and your family, and a one size fits all color scheme just won’t work. A color consultation takes into account your existing furniture, lighting, architectural features, and your interior style goals to create a personalized color palette that works for your home. Let’s bring color and harmony into your space.

A color design process that's science based

There’s no guesswork with a science-based color plan. I use the same color system that paint manufacturers use to make and manage their product. Data taken from color measurements of your home, combined with a scientific framework that uses hue, value, and chroma takes the stress out of finding the right color combinations for your home.

Choosing color for your home is straightforward right? Wrong!

Choosing color for your home is straightforward right? Wrong! I can’t tell you how many times I’ve chosen a white that was too bright or the wrong shade of blue. I’ve made several costly errors where color and design are concerned. This is where Diana comes in! Her expertise and knowledge of colors takes the guess work out of decorating. I recently needed a white color for my dining room. She came over, measured the wall color and talked me through the best choices. It took the guesswork out of it for me. She is truly an expert in her field.

I thoroughly enjoyed collaborating with Diana

I thoroughly enjoyed collaborating with Diana to visualize my space and explore new ways to decorate and style my home. Diana assisted me by helping me with some challenging areas in my home and transforming them into more functional and usable spaces for my family. She was very easy to work with and gave me suggestions on how to style my home while complementing the existing wall colors. The ability to see the different options was essential in helping me visualize the spaces and their potential uses. I appreciated her mood boards, which offered ideas not only on color schemes but also on various décor items that could be incorporated throughout the space. I would highly recommend Diana to anyone seeking assistance in designing their space.

With Diana's help I completely reconstruct the style in our home into exactly what we wanted

Diana was able to help my husband and I completely reconstruct the style in our home into exactly what we wanted. Her use of Photoshop was incredibly helpful in allowing us to discover our own style for our home and showing us various alternatives. We were able to compare before and after photos with different wallpapers and colors, as well as learn about how colors can really transform a space. She is also incredibly talented at gauging her clients’ personal taste, even when the clients are unsure of what they want. My husband and I were able to figure out a cost-effective way of reconstructing our house, without making an expensive mistake. We fully recommend Color and Harmony for everyone wanting to upgrade their home!

Diana played a pivotal role in assisting me

Diana played a pivotal role in assisting me with not only selecting new cabinet colors but also in redesigning the overall aesthetic of my kitchen and living room spaces. She listened attentively to my preferences and ideas, helping to build the story and concept of what I envisioned for my space. She provided multiple color suggestions that complemented the existing flooring and countertops, ensuring the shades and hues were appropriate. Based on her color samples, I was able to evaluate the color options to determine the best fit for my needs. Additionally, Diana helped me visualize the changes to my space through her mock-ups, which significantly aided in envisioning the transformations. She was highly responsive and offered excellent suggestions for additional décor to align with the overall changes I sought. Diana brought samples of décor items such as rugs and fabrics for pillows, allowing me to see how they would integrate cohesively. Her mock-ups enabled me to envision the complete changes and understand how all the elements worked together to create a harmonious space. I would highly recommend Diana and plan to use her again in the future.

Diana did a wonderful job

Diana did a wonderful job coming to our house and helping me give a particular room more purpose. She helped with how to arrange the furniture and the colors that would be most comfortable for our home environment. I also sought her advice when we had some new construction done to the exterior of our house. She was able to take a picture and make color suggestions that would complement our home.

Our experience with Diana was exactly what we needed!

Our experience with Diana was exactly what we needed! We had mold in our bathroom that was affecting my health, and we needed help quickly. Diana did exactly what she said she would in a very timely way. She made the work of the construction team so much easier for them by doing extra work that she knew would move things along. She did measurements and floor plans she knew they would need, and they were grateful to her for the extra work.

I am a very indecisive person, and she helped me in ways that I needed. Because of our water damage we had more to do, and I wanted her help for it all. She helped me choose tile, carpet for the rest of the house, paint colors, fixtures, a new tub and decor. Her suggestions helped so much, and her taste is impeccable. At the same time, she listened to what I liked and wanted. It came together perfectly. When she speaks about decorating you can tell it is a passion for her. She was an absolute blessing to us, and it was so much fun to work with her.

Diana is a wildly talented and thoughtful person

Diana is a wildly talented and thoughtful person. She has such an eye for design and such kindness in how she encouraged me to be confident in my design choices. I feel more capable investing in items and selecting colors in my spaces, whereas before, I would either pick whatever was popular or on sale. Now, my home is a much more accurate reflection of who I am and who my family is and I couldn’t have done it without Diana!
