The prime labeling of sunflower graph is given in13.

Paint frosting with food coloring. Hence all the given graphs are cycle graphs. In the mathematical discipline of graph theory a wheel graph is a graph formed by connecting a single universal vertex to all vertices of a cyclea wheel graph with n vertices can also be defined as the 1 skeleton of an n 1 gonal pyramidsome authors write w n to denote a wheel graph with n vertices n 4. Graph ii has 4 vertices with 4 edges which is forming a cycle pq qs sr rp.

Interactive color wheel generator chart online. Get color codes and color schemes. Colors that look good together are called a color harmony.

Artists and designers use these to create a particular look or feel. The rainbow coloring of corona of flower graph is proved to be 3. The edges of a wheel which include the hub are called spokes skiena 1990 p.

The color wheel was invented in 1666 by isaac newton who mapped the color spectrum onto a circle. The problem is given m colors find a way of coloring the vertices of a graph such that no two adjacent vertices are colored using same color. The helm h n is the graph obtained from a wheel by attaching a pendant edge at each vertex of the n cycle.

A graph coloring is an assignment of labels called colors to the vertices of a graph such that no two adjacent vertices share the same color. 78 is a graph that contains a cycle of order n 1 and for which every graph vertex in the cycle is connected to one other graph vertex which is known as the hub. The chromatic number x g chig x g of a graph g g g is the minimal number of colors for which such an.

A flower is the graph obtained from a helm by joining each pendant vertex to the central vertex of the helm. Graph iii has 5 vertices with 5 edges which is forming a cycle ik km ml lj ji. A graph coloring for a graph with 6 vertices.

It is impossible to color the graph with 2 colors so the graph has chromatic number 3. A wheel graph wn of order n sometimes simply called an n wheel harary 1994 p. In complex analysis domain coloring or a color wheel graph is a technique for visualizing complex functions by assigning a color to each point of the complex planeby assigning points on the complex plane to different colors and brightness domain coloring allows for a four dimensional complex function to be easily represented and understood.

The color wheel is the basis of color theory because it shows the relationship between colors. A wheel graph is obtained from a cycle graph c n 1 by adding a new vertex. Graph coloring problem is to assign colors to certain elements of a graph subject to certain constraints.

Other authors instead use w n to denote a wheel graph with n1 vertices n 3.
