Digital oil painting, also known as Painting by Numbers or Paint by Number, involves computer-standardized color mixing based on RGB values to generate color data. Software then breaks this data into numerical codes representing different color blocks. These software-generated codes must be manually painted by the artist, who simply fills in the designated numbered color blocks with the corresponding paint colors to create a richly layered image. So what should beginners pay attention to when painting digital oil paintings? Here are some key points:
1. When Painting by Numbers, you'll encounter both large and small color blocks. Pay attention to brush selection: use a large brush for expansive areas and a small brush for detailed sections. It's best to prepare brushes in three sizes—large, medium, and small—so you can switch brushes promptly for different block sizes. This ensures a more uniform finish.
2. When applying color, ensure no white base shows through. Apply the first color slightly thicker to fully cover the edges of the block. Then, apply the next color over the previous one. This creates a richer, more substantial look and prevents the base from showing.
3. Some colors have poor coverage and require two or three layers, such as lemon yellow, light green, and bright red. When the first layer isn't even, apply the second layer carefully. Improper application can easily cover surrounding colors, causing color chaos. Exercise caution here.
4. After applying the first color, wait until it is completely dry before applying the second. Applying colors before the first layer is dry will cause them to blend, resulting in a muddy appearance.
5. Digital oil painting styles vary—some lean toward Impressionism, others toward realism, while some replicate masterpieces. Adapt your technique to the subject matter: use thick, textured strokes for Van Gogh-inspired works, and fine, even strokes for realistic pieces.
6. If you make a mistake, don't panic. Acrylic paint has excellent coverage. Once the incorrect color dries, simply paint over it with the correct color.
These are the key points to remember when painting by numbers. Make sure to memorize each one and keep them in mind throughout your painting process.
