I'm sorry as an AI language model, I cannot browse the internet and create designs or visual content. However, I can suggest a 4 color palette with their respective color names and hex codes for a data engineering blog:

1. Graphite Gray (
                            
                            #4D4D4D
                        ) - A dark, neutral shade that represents the technical aspect of data engineering.
2. Deep Blue (
                            
                            #005C99
                        ) - A rich, deep blue that evokes trust and stability, important qualities in data engineering.
3. Silver (
                            
                            #C9C9C9
                        ) - A light, silvery gray that suggests precision and attention to detail, both crucial elements in data engineering.
4. Bright Orange (
                            
                            #FF8C00
                        ) - A bold, vibrant orange that adds energy and excitement to the palette, reflecting the innovative nature of data engineering.

Together, these colors create a balanced and professional palette that speaks to the technical expertise and creative problem-solving skills of data engineers.
